Dalevi, Mathias. "S-Band Antenna Array". Thesis, Uppsala University, Astronomy and Space Physics, 2010. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-126302.
Testo completoThis report presents concepts for a planar active electronically scanned antenna(AESA). The goal of the project was to devlop a low-weight, low profile, thin, S-band antenna with wide-scan angle capabilities. In the final concept the service aspects of the T/R-modules was also taken into acount in order to allow easy and fast replacements of these components. The antenna was designed and optimised using the commercial software Ansoft HFSS. A prototype of the antenna was constructed and later measured and verified. The final concept is a 2m×2m antenna with an estimated weight of around 320 kg, around 11 cm thick (where the thickness of the antenna element is 1.76 cm) and has a maximum scan angle range of more than 45 degrees (with <–10dB active reflection) in the frequency band 3–3.5 GHz.

Testo completoDetta arbete studerar brustålighet hos neurala nätverk för klassificering av \textit{låg sannolikhet för avlyssning} (LPI) radars modulationstyp. Specifikt testas ett antal arkitekturer baserade på faltningsnätverk och evalueras i fyra olika syntetiska brusmiljöer. Tester genomförda på data med Gaussiskt brus visar att klasificeringsfelet är ökande med ett minskande signal-till-brusförhållande. Om man låter nätverken träna på alla brusnivåer som ingår i datan uppnås en högsta pricksäkerhet om 70.8 % vid ett signal-till-brusförhållande på -6 dB. Vidare tester tyder på att nätverken presterar sämre på låga signal-till-brusförhållanden om de inte finns med i träningsdata och ger i allmänhet mellan 10-20 % sämre pricksäkerhet. Om de mellersta brusnivåerna inte finns med i träningsdata presterar nätverken lika bra som när de finns med i träningsdata. Om träningsdata och testdata genereras med olika parameterar presterar nätverken dåligt. För dessa tester uppnås en högsta pricksäkerhet om 22.0 % vid ett signal-till-brusförhållande på -6 dB. Den sista brusmiljön som testades på använder sig av telekom signaler som om de vore brus istället för Gaussiskt brus. I detta fall är LPI och telekom signalerna väl skiljda i frekvens och nätverken presterar lika bra som tester i Gaussiskt brus med högt signal-till-brusförhållande. Högsta pricksäkerhet som uppnåts på dessa tester är 80.3 % i mellanhög brusnivå. Detta arbete bidrar även med nätverk som presterar bra utan att data behöver signalbehandlas innnan den kan klassificeras samt genererar data på ett mer realistiskt vis än tidigare litteratur inom detta område. Utan att signalbehandla data uppnåddes en högsta pricksäkerhet om 64.9 % vid ett signal-till-brusförhållande på -6 dB. Den mer realistiska datan genereras så att dess startpunkt är slumpmässig. I litteraturen brukar startpunkten inkluderas och uppnår på så vis överlag pricksäkerheter som är ungefär 20 % högre än de tester som genomförs i detta arbete. I verkliga applikationer är det sällan man kan identifera en signals startpunkt med säkerhet.

Testo completoA device has been designed that cancels the leakage signal between the transmit and receive antenna in a Stepped Frequency Continuous Wave Ground Penetrating Radar. The front end of the radar operates at high signal levels and, as a result, a large signal is coupled directly from the transmit to the receive antenna. This signal uses a signiï¬ cant part of the dynamic range of the data-capturing device, an analogue-to-digital converter (ADC). The objective of this cancellation is thus to increase the effective instantaneous dynamic range of the radar system. Simulations show that 10-bit amplitude and phase resolution in the digital cancellation circuit would achieve maximum cancellation in the presence of phase noise and other sources of error. This result is conï¬ rmed when the hardware is tested. The device was constructed and operates as intended. Tests show that cancellation exceeding 53dBm is possible through careful calibration. It was concluded that the device could successfully be integrated into the SFCW GPR and that it would achieve an increase in the instantaneous dynamic range.

Testo completoThis thesis provides an original approach of the quantum illumination radar using the quantum information theory to study the evolution of quantum correlations in a radar system. We first propose a parallel between the classical radar theory and the quantum radar theory to determine similarities anf differences insisting on the last point. The quantum illumination radar uses pairs of entangled photons to detect the absence of the presence of a low-reflecting object into a bright thermal background that disturbs the detection. Using the parallel between the radar theories, research has been done on the atmospheric influence on the evolution of entanglement of the system of photons in the radar, and on the evolution of quantum correlations quantified by the quantum discord. The objective of research was to show a link between the quantum discord and the binary decision strategy of the quantum radar. Results suggest this link even if improvements should be required on the tested models. It should permit to study practical situations particularly if we think about a possible experiment on a quantum illumination protocol

Testo completoi.e. RAKE, zero-forcing decorrelator, linear minimum mean-squared error (LMMSE) multiuser receivers, within a single-cell setting over generalized time-varying GWSSUS - Rayleigh/Ricean - fading channels via random matrix theoretic tools. Assuming maximal-ratio combining (MRC) of resolved frequency - multipath - diversity channels due to wideband transmission, the signal-to-interference ratios (SIRs) with multichannel multiuser receivers that set the basis for further derivations are statistically characterized. The information-theoretic ergodic and outage sum-rates spectral efficiencies are then derived and analyzed.

Testo completoThe automatic recognition of non-cooperative targets is very important in various fields. This is the case for applications in aviation and maritime uncertain environment. Therefore, it’s necessary to introduce innovative methods for radar targets treatment and identification.The proposed methodology is based on the Knowledge Discovery from Data process (KDD) for a complete chain development of radar images recognition by trying to optimize every step of the processing chain.The experimental system used is based on an ISAR image acquisition system in the anechoic chamber of ENSTA Bretagne. This system has allowed controlling the quality of the entries in the recognition process (KDD). We studied the stages of the composite system from acquisition to interpretation and evaluation of results. We focused on the center stage; data mining considered as the heart of the system. This step is composed of two main phases: classification and the results of classifiers combination called decisional fusion. We have shown that this last phase improves results for decision making by taking into account the imperfections related to radar data, including uncertainty and imprecision.The results across different classification techniques as a first step (kNN, SVM and MCP) and decision fusion in a second time (Bayes, majority vote, belief theory, fuzzy fusion) are subject of an analytical and comparative study in terms of performance

Testo completoI den här avhandlingen undersöker Lovisa Skånfors barns sociala vardagsliv i förskolan. Det specifika syftet är att bidra med kunskap om barns gemensamma sociala kunskaper i förskolans kamratkulturer, både vad gäller dess innehåll och hur de etableras och upprätthålls. Författaren har genom ett etnografiskt arbetssätt följt barns gemensamma aktiviteter på en 3-5-årsavdelning i en svensk förskola, under 1,5 år. Resultatet visar att barns gemensamma sociala kunskaper handlar om hur man kan skapa och upprätthålla relationer och hur man kan distansera sig från relationer. Barns sociala relationer skapas och upprätthålls i relation till olika sociala resurser (rätt ålder, specifika kompetenser och tidigare etablerade relationer). Barn skapar dessutom distans till andra barn och vuxna genom att på olika sätt dra sig undan i förskolekontexten. Resultatet visar också att det tycks finnas en spänning mellan barnens gemensamma sociala kunskaper och de normer om kollektivitet som explicit formuleras i den studerade förskolekontexten. Avhandlingen vänder sig till forskare och praktiker med intresse för frågor kring förskola och förskolebarns sociala samspel.
