Abstract:

We discuss the modeling of propagation of a quasi-monochromatic radio signal, represented by a coherent pulse sequence, in a non-stationary multipath radio channel. In such a channel, signal propagation results in the observed frequency shift for each ray (Doppler effect). The modeling is based on the assumption that during propagation of a single pulse a channel can be considered stationary. A phase variation in the channel transfer function is shown to cause the observed frequency shift in the received signal. Thus, instead of measuring the Doppler frequency shift, we can measure the rate of variation in the mean phase of one pulse relative to another. The modeling is carried out within the framework of the method of normal waves. The method enables us to model the dynamics of the electromagnetic field at a given point with the required accuracy. The modeling reveals that a local change in ionospheric conditions more severely affects the rays whose reflection region is in the area where the changes occur.

Abstract. Multi-frequency observations of E-region coherent backscatter from decametre waves reveal that auroral echoes tend to comprise two spectral components superimposed, one at low Doppler shifts, below 250 ms-1, and the other Doppler shifted to near the ion-acoustic speed or above, up to 800 ms-1. The low Doppler shift component occurs at all look directions; Doppler shifts near the ion acoustic speed occur when looking at low flow angles along the direction of the electron drift in the electrojet, and Doppler shifts in excess of the ion acoustic speed occur at intermediate flow angles. The latter population appears most commonly at radar frequencies near 10–12 MHz, with its occurrence decreasing dramatically at higher frequencies. The velocity of the high Doppler shift echoes increases with increasing radar frequency, or irregularity wave number k. The velocity of the low Doppler shift population appears to be suppressed significantly below the line-of-sight component of the electron drift. Initial estimates of the altitude from which scatter occurs suggest that the high Doppler shift echoes originate from higher in the E-region than the low Doppler shift echoes, certainly in the eastward electrojet. We discuss these observations with reference to the theories of de/stabilization of two-stream waves by electron density gradients and electrostatic ion cyclotron waves excited by field-parallel electron drifts.Key words.

Abstract:

Shift-frequency jamming is generally used to form range false targets for ground-based early-warning radar systems; the frequency shift value of such interference is larger than the Doppler shift value of the moving target, and the key element to suppress the shift-frequency jamming is the frequency shift value estimation. However, in the low- or medium-pulse repetition frequency (PRF) mode, it is challenging to estimate the accurate frequency shift due to the velocity ambiguity. To solve this problem, a novel sparse Doppler-sensitive waveform is designed based on the ambiguity function theory, where the basic idea is to design a waveform sensitive to a specific Doppler but insensitive to other Dopplers; therefore, this waveform can recognize the specific Doppler of the target unambiguously. To apply the designed waveform in practice, the detection and estimation processing flow is provided based on the waveform diversity technique and the family of the sparse Doppler-sensitive waveforms. Simulation experiments are presented to validate the efficiency of the proposed method, and we conclude that the advantage of this method is that it can be used to confirm the specific Doppler of the target unambiguously with few pulses even under the condition of a low PRF.

Abstract:

The rotational Doppler effect—the angular version of the Doppler effect—shows a frequency shift phenomenon happening when light passes through a rotating object and its angular momentum is changed. The rotational Doppler effect has been widely studied with various light waves based on different angular momentum transform mechanisms and successfully utilized to detect the rotation of objects. However, these studies are mostly limited to linear optics. As the rotational Doppler effect is closely related to the frequency degree of freedom and frequency conversion always happens in nonlinear optics, it is of great significance to explore the rotational Doppler effect in nonlinear optics. Although nonlinear rotational Doppler phenomena have been observed in second-harmonic generation with circularly polarized Gaussian fundamental light and a rotating nonlinear crystal, there is still the open challenge of how to realize Doppler frequency shift conversion (similar to conventional nonlinear frequency conversion), such as doubling or tripling. Here we report the experiment observation of rotational Doppler shift conversion in nonlinear optics. We demonstrate the tripling of a rotational Doppler frequency shift in third-harmonic generation of a spatially structured fundamental wave. Frequency shifts can be extracted from the intensity beating signals with the interference of two components of vector fields with opposite topological charges and the measured modulation frequency of the beating signal for the generated third harmonic. Our results will excite more research on nonlinear optics with spatially structured light, and our method may create opportunities for precision measurement of frequency shifts.

This research described the Doppler shift effect for the communication systems. The mobile station moves with various velocities around the building’s environment. Doppler’s shift influences the communication systems. The frequency communication was used 10 GHz and its influenced by atmospheric attenuation. This research consisted of propagation with LOS and NLOS conditions, mobile station velocity variation, height buildings variation, and transmitter power variation. This research described frequency maximum at Doppler shift, coherence time, and signal to noise ratio. More increase Doppler shift of coherence time caused signal noise ratio to decrease.

Abstract:

A method to extend Doppler frequency discrimination tolerance is proposed for quick acquirement PN-code and Doppler frequency in TDMA burst spread spectrum communication system. According to Doppler’s different impacts on the correlation Peak and data demodulation, PN-code is acquired through single channel matched-filters, and parallel multi-channel correlators are used in the data demodulation branch channel. Thus, with using frame head prior information in data channel instead of traditional Cross-Product Automatic Frequency Control (CPAFC), the Doppler frequency shift discrimination tolerance is extended. Simulation and experiment show that frequency and PN-code can be acquired in several data periods, and synchronous time and the resources consumption are effectively reduced.

Abstract:

Direct Position Determination (DPD) of coherent pulse trains using a single moving sensor is considered in this paper. Note that when a large observation window and relative maneuvering course between emitter and receiver both exist, the localization accuracy of Doppler frequency shift only based DPD will decline because of the noticeable Doppler frequency shift variations. To circumvent this problem, a Doppler frequency shift and Doppler rate based DPD approach using a single moving sensor is proposed in this paper. First, the signal model of the intercepted coherent pulse trains is established where the Doppler rate is taken into consideration. Then, the Maximum Likelihood based DPD cost function is given, and the Cramer–Rao lower bound (CRLB) on localization is derived whereafter. At last, the Monto Carlo simulations demonstrate that in one exemplary scenario the Doppler frequency shift variations are noticeable with a large observation window and the proposed method has superior performance to the DPD, which is only based on the Doppler frequency shift.

Abstract:

A novel approach employing 4G LTE Cellular Technology for Test Range Telemetry is presented. Providing aeronautical mobile telemetry using commercial off the shelf (COTS) cellular equipment poses many challenges, including: Three-dimensional (3D) coverage, need for uninterrupted high data throughputs, and very high Doppler speeds of the Test Articles (TA). Each of these requirements is difficult to meet with a standard cellular approach. We present a novel architecture that provides 3D coverage over the span of a test range, allowing the TA to establish a radio link with base stations that have a manageable Doppler due to the reduced projected TA speed on the radio link line. Preliminary results illustrate that a variety of flight plans can be accommodated with commercial LTE technology by employing LTE’s mobility mechanisms and adding centralized control. The resulting network architecture and Radio Access Network topology allow very high throughputs to be delivered throughout the test range with a judicious placement of base stations.

Abstract:

This dissertation is focused on developing the new target localization and the target velocity estimation methods for frequency-only multi-input, multi-output (MIMO) radar systems with widely separated antennas. If the frequency resolutions of the transmitted signals are enough, only the received frequencies and the Doppler shifts can be used to find the position of the target. In order to estimate the position and the velocity of the target, most multistatic radars or radar networks use multiple independent measurements from the target such as time-of-arrival (TOA), angle-of-arrival (AOA) and frequency-of-arrival (FOA). Although, frequency based systems have many advantages, frequency based target localization methods are very limited in literature because of the fact that highly non-linear equations are involved in solutions. In this thesis, alternative target localization and the target velocity estimation methods are proposed for frequency-only systems with low complexity. One of the proposed methods is able to estimate the target position and the target velocity based on the measurements of the Doppler frequencies. Moreover, the target movement direction can be estimated efficiently. This method is referred to as "
Target Localization via Doppler Frequencies - TLDF"
and it can be used for not only radar but also all frequency-based localization systems such as Sonar or Wireless Sensor Networks. Besides the TLDF method, two alternative target position estimation methods are proposed as well. These methods are based on the Doppler frequencies, but they requires the target velocity vector to be known. These methods are referred to as "
Target Localization via Doppler Frequencies and Target Velocity - TLD&
V methods"
and can be divided two sub-methods. One of them is based on the derivatives of the Doppler Frequencies and hence it is called as "
Derivated Doppler - TLD&
V-DD method"
. The second method uses the Maximum Likelihood (ML) principle with grid search, hence it is referred to as "
Sub-ML, TLD&
V-subML method"
. The more realistic signal model for ground based, widely separated MIMO radar is formed as including Swerling target fluctuations and the Doppler frequencies. The Cramer-Rao Bounds (CRB) are derived for the target position and the target velocity estimations for this signal model. After the received signal is constructed, the Doppler frequencies are estimated by using the DFT based periodogram spectral estimator. Then, the estimated Doppler frequencies are collected in a fusion center to localize the target. Finally, the multiple targets localization problem is investigated for frequency-only MIMO radar and a new data association method is proposed. By using the TLDF method, the validity of the method is simulated not only for the targets which are moving linearly but also for the maneuvering targets. The proposed methods can localize the target and estimate the velocity of the target with less error according to the traditional isodoppler based method. Moreover, these methods are superior than the traditional method with respect to the computational complexity. By using the simulations with MATLAB, the superiorities of the proposed methods to the traditional method are shown.

Abstract:

Approved for public release; distribution is unlimited
An error probability analysis is done for a DFT based, M-ary frequency-shift keying (MFSK) communications system employing fast frequency-hopped spread spectrum signals. A linear combination procedure referred to as noise-normalization is employed at the receiver to minimize the effects of partial-band interference, which is modeled as additive Gaussian noise. The performance of the receiver is studied as a function of signal Doppler shift and type of windowing used in the DFT. The use of fast frequency-hopped spread spectrum is found to improve the performance of the DFT based receiver in all but the most severe cases of Doppler shift. The use of a non-uniform window (i. e., a Hamming window) to improve receiver performance is effective only in the presence of large Doppler shifts. The amount of Doppler shift necessary to warrant the use of a non-uniform window depends on the amount of jamming noise power at the receiver, but is relatively insensitive to the frequency hop rate used

Abstract:

Ce travail présente une étude des raies de plasma observées à l'aide du radar à diffusion incohérente EISCAT. Le travail est centré sur deux points. Tout d'abord, la conception d'une expérience raies de plasma pour le radar EISCAT, avec une résolution spatiale améliorée. Puis, la comparaison de données raies de plasma acquises avec le radar EISCAT avec une théorie améliorée sur l'intensité et le décalage Doppler en fréquence des raies de plasma. Pour améliorer la résolution spatiale, nous avons conçu la première expérience raies de plasma mettant en oeuvre la technique du code alternatif. Cette expérience a été tournée avec succès avec une résolution spatiale de 3 km au lieu de 40-50 km obtenu avec les techniques conventionnelles. Parce qu'il est très difficile de construire un modèle cohérent de la fonction de distribution des vitesses des électrons satisfaisant tous les intervalles d'énergies pertinents, nous avons construit une représentation adéquate de la distribution des vitesses des électrons en séparant la distribution en deux populations : la thermique et la suprathermique. La population thermique est représentée par la fonction de Spitzer qui tient compte de l'effet d'un champ électrique et/ou d'un gradient de température. La population suprathermique est déduite du flux angulaire d'énergie calculé grâce à un modèle numérique du transport des électrons. Un code numérique a été développé pour calculer la fonction diélectrique et la fonction réduite de distribution des vitesses pour toutes distributions des vitesses à deux dimensions dont nous avons besoin pour modéliser l'intensité et le décalage Doppler en fréquence des raies de plasma. Nous avons pu reproduire les caractéristiques de l'intensité et du décalage Doppler en fréquence des raies de plasma avec des données mesurées avec le radar VHF EISCAT. En particulier, nous avons identifié deux pics étroits dans la distribution des vitesses des suprathermiques comme la signature de la photo-ionisation de N_2 et O. Ces pics ont été observés sur les données. L'effet d'un gradient de température - qui produit une correction importante au décalage Doppler des raies de plasma - a été pris en compte plus précisement que précédemment en calculant numériquement les intégrales singulières, au lieu d'utiliser les premiers termes d'une expansion en séries comme auparavant. C'est important car cela a permis pour la première fois à un modèle de reproduire précisément l'intensité et le décalage Doppler des raies de plasma mesurés par une expérience EISCAT.

Abstract:

AbstractIn this chapter, the authors review basic concepts about echolocation, the variety of animals known to echolocate, the production of echolocation signals, the different types of echolocation signals, the hearing anatomy, and how echolocating animals use echolocation. The differences between echolocation signals in air versus water are discussed. Echolocation abilities have been studied intensively in bats and toothed whales, the two groups with the most sophisticated echolocation systems in terms of physiological specializations and performance. Echolocation has also been documented in oilbirds and swiftlets; and a crude form of echo-based orientation may be present in tenrecs and shrews.The authors emphasize that the ability to produce ultrasonic sounds does not necessarily imply an echolocation function. Most echolocators (i.e., a select group of bats, toothed whales, oilbirds, and swiftlets) use broadband clicks, but the majority of bats produce tonal echolocation signals of constant frequency, frequency modulation, or a combination of both. Most echolocators cannot broadcast and receive echolocation signals at the same time but separate each outgoing pulse from its returning echoes in time to detect the echoes and avoid masking caused by overlap with the outgoing signal. However, three families of bats can tolerate pulse-echo overlap and use the Doppler shift to identify prey items.A primary advantage of echolocation is allowing animals to operate and orient independently of ambient light conditions. At the same time, information leakage is a primary disadvantage of echolocation. The signals used in echolocation are audible to many other animals, such as competing conspecifics, predators, and prey.

Abstract:

AbstractMany applications of particle accelerators require beam cooling, which refers to a reduction of the beam phase space volume or an increase in the beam density via dissipative forces. In electron and positron storage rings cooling naturally occurs due to synchrotron radiation, and special synchrotron-radiation damping rings for the production of low-emittance beams are an integral part of electron-positron linear colliders. For other types of particles different cooling techniques are available. Electron cooling and stochastic cooling of hadron beams are used to accumulate beams of rare particles (such as antiprotons), to combat emittance growth (e.g., due to scattering on an internal target), or to produce beams of high quality for certain experiments. Laser cooling is employed to cool ion beams down to extremely small temperatures. Here the laser is used to induce transitions between the ion electronic states and the cooling exploits the Dopper frequency shift. Electron beams of unprecedentedly small emittance may be obtained by a different type of laser cooling, where the laser beam acts like a wiggler magnet. Finally, designs of a future muon collider rely on the principle of ionization cooling. Reference [1] gives a brief review of the principal ideas and the history of beam cooling in storage rings; a theoretical dicussion and a few practical examples can be found in [2].
