Abstract:

The phased array multi-function radar is an effective solution to the requirement for simultaneous surveillance and multiple target tracking. However, since it is performing the jobs usually undertaken by several dedicated radars its radar time and energy resources are limited. For this reason, and also due to the large cost of active phased array antennas, it is important for the strategies adopted in the control of the radar to be efficient. This thesis investigates and develops efficient strategies for multi-function radar control and tracking. Particularly the research has focused on the u

Abstract:

The risk of collision increases, as the number of cars on the road increases. Automotive radar is an important way to improve road traffic safety and provide driver assistance. Adaptive cruise control, parking aid, pre-crash warning etc. are some of the applications of automotive radar which are already in use in many luxury cars today. In automotive radar a commonly used modulation waveform is the linear frequency modulated continuous waveform (FMCW); the return signal contains the range and velocity information about the target related through the beat frequency equation. Existing techniques

The multifunction radar, aided by advances in electronically steered phased array technology, is capable of supporting numerous, differing and potentially conflicting tasks. However, the full potential of the radar system is only realised through its ability to automatically manage and configure the finite resource it has available. This thesis details the novel application of agent systems to this multifunction radar resource management problem. Agent systems are computational societies where the synergy of local interactions between agents produces emergent, global desirable behaviour. In th

Abstract:

Accurate rainfall forecasting using weather radar imagery has always been a crucial and predominant task in the field of meteorology [1], [2], [3] and [4]. Competitive Radial Basis Function Neural Networks (CRBFNN) [5] is one of the methods used for weather radar image based forecasting. Recently, an alternative CRBFNN based approach [6] was introduced to model the precipitation events. The difference between the techniques presented in [5] and [6] is in the approach used to model the rainfall image. Overall, it was shown that the modified CRBFNN approach [6] is more computationally efficient

Abstract:

The goal of this thesis study is to investigate the Ambiguity Function Technique for target detection in phase-coded continuous wave radar. Also, phase shift keying techniques are examined in detail. Continuous Wave (CW) Radars, which are also known as Low Probability of Intercept (LPI) radars, emit continuous signals in time which are modulated by either frequency modulation or phase modulation techniques. Modulation of the transmitted radar signal is needed to estimate both the range and the radial velocity of the detected targets. In this thesis, Phase Shift Keying (PSK) techniques such as

Continuous Wave (CW) radars are preferred for their low probability of intercept by the other receivers. Frequency modulation techniques, the linear frequency modulation (LFM) technique in particular, are commonly used in CW radars to resolve the range and the radial velocity of the detected targets. The conventional method for target detection in a linear FMCW radar makes use of a mixer followed by a low-pass filter whose output is Fourier transformed to get the range and velocity information.

Abstract:

Weather radar imagery is important for several remote sensing applications including tracking of storm fronts and radar echo classification. In particular, tracking of precipitation events is useful for both forecasting and classification of rain/non-rain events since non-rain events usually appear to be static compared to rain events. Recent weather radar imaging-based forecasting approaches [3] consider that precipitation events can be modeled as a combination of localized functions using Radial Basis Function Neural Networks (RBFNNs).

Furthermore, the quality of the NIRS signals was poor in a significant portion of the investigated sample, reducing clinical potential.

Abstract:

Synthetic aperture radar (SAR) was originally designed as an airborne ground-imaging radar technology. But it has long been desired to also be able to use SAR imaging systems to detect, locate, and track moving ground targets, a process called Ground Moving Target Indication (GMTI). Unfortunately, due to the nature of how SAR works, it is inherently poorly suited to the task of GMTI. SAR only focuses targets and image features that remain stationary during the data collection. A moving ground target therefore does not focus in a conventional SAR image, which complicates the process of performi

Abstract:

This diploma thesis deals with a spatial imaging of targets using time-domain radar responses on the max(t,0) pulse. The problem is formulated for both perfectly electrically conductive and dielectric objects. The main aim of the thesis includes a code implementation calculating the profile functions of an unknown object from the mentioned time responses and a code for the subsequent reconstruction of an object in the MATLAB environment. A graphical user interface was created for testing purposes. The 3D probability function technique was used for the final reconstruction. The implemented tech

Abstract:

Neuronal nicotinic acetylcholine receptors (nAChRs) are ligand-gated ion channels that influence neurotransmitter release, hence constituting a key component of the physiological mechanisms of neuronal signalling. This thesis is concerned with the properties of the a4P2 nAChR, the most abundant nAChR in the brain, and the major contributor to the central effects of nicotine. The a4P2 nAChR is made up of five subunits, which in heterologous systems can assemble into at least two different stoichiometries: the high sensitivity (HS) (a4h(P2)3 stoichiometry and the low sensitivity (LS) (a4)3(p2)2

Abstract:

Au cours des deux dernières décennies, les signaux chaotiques ont été de plus en plus pris en compte dans les télécommunications, traitement du signal ou transmissions sécurisées. De nombreux articles ont été publiés qui étudient la densité spectrale de puissance (DSP) des signaux générés par des transformations spécifiques. La concentration sur la DSP est due à l'importance de la fréquence dans les télécommunications et la transmission sécurisée. Grâce au grand nombre de systèmes sans fil, la disponibilité des fréquences de transmission et de réception est de plus en plus rare pour les commun

Abstract:

The α4β2 nicotinic acetylcholine receptor (nAChR) assembles in two alternate forms, (α4β2)₂α4 and (α4β2)₂β2, which display stoichiometry-specific agonist sensitivity. Being heteromeric pentameric ligand-gated ion channels (pLGIC), α4β2 receptors are activated by binding of agonist to sites located at the α4(+)/β2(-) interfaces. These interfaces are present in both stoichiometries they are unlikely to contain structural differences conferring specific properties to (α4β2)₂α4 and (α4β2)₂β2 receptors. In contrast, the auxiliary subunit can be either α4 or β2, leading to stoichiometry-specific β2(

Abstract:

The main aim of using radars in industrial safety system is to detect the presence of target accurately. The conventional methods of radar target detection algorithm such as the Cell averaging constant false alarm rate method (CA-CFAR), Greatest of constant false alarm method (GO-CFAR) and the Smallest of constant false alarm rate method (SO-CFAR) has their own disadvantage when it comes to precise target detection which is a key factor for a safety system. This thesis investigates the above mentioned conventional CFAR algorithms for its pros and cons in target detection and proposes a new and
