Повний текст джерелаThis report is focused on Through-the-wall surveillance (TTS) using UWB radar, with the objective of developing a complete information processing pipeline (IPP) which can be used by different types of imaging radar. To do this, we want to take into account any a priori information, nor on the target, or their environmental context. In addition, the IPP must meet criteria of adaptability and modularity to process information from two types of radar, including pulsed and FMCW developed in two projects that are part of the work of this thesis. Radar imaging is an important point in this context ; we approach it by combining backprojection and trilateration algorithms and show the improvement with the use of a CFAR detector taking into account the shape of the targets signatures.The development of the IPP is our main contribution. The flow of radar images obtained is divided into two parts. The first dynamic sequence contains moving targets are tracked by a multiple hypothesis approach. The second static sequence contains stationary targets and interior walls that are highlighted by Radon transformbases approach. We developed a simulator operating in time and frequency domain to design the algorithms of the IPP and test their robustness. Several simulated scenarios and experimental measurements show that our IPP is relevant and robust. It is thus validated for both radar systems

Wind data obtained between 1999 and 2016 from measuments by meteor radar at Cachoeira Paulista (22.7°S, 45.0°W), Brazil, were used to investigate the behavior of the dynamics on upper mesosphere and lower thermosphere region, the interannual variability in the winds, in the diurnal tide and 2-day wave amplitudes and the possible causes. The results show that zonal wind is characterized by a semiannual variation below 90 km and annual above, while the meridional wind exhibits an annual cycle at all altitudes. Monthly winds did not show quasi-biennial variation (QBO), however the seasonal winds in the zonal direction observed during the summer and fall show QBO variations type in altitudes below 90 km. The results also suggest that the zonal and meridional winds are intensified during the years of solar maximum, especially in the summer and winter seasons. The monthly amplitudes of diurnal tide show an annual variation, in which the amplitudes are greater during the eastward phase of QBO at 30 hPa. The spectrum obtained from the deseasonalized amplitudes shows a 26 months peak in the meridional component, which may to be associated with stratospheric QBO phase. The modulation of the diurnal tide amplitude by QBO shows a quasi ten-year variation, and is stronger for the solar cycle maximum. The amplitude of the 2-day wave exhibit interannual variability, however, do not shows to be affected by the QBO phase during the summer season. The amplitudes of the 2-day show interannual variability, but, only in winter it is affected by the QBO phase. Good agreement between the variation of the amplitude of the 2-day wave for meridional wind and the solar radio flux was observed for most of the summers with a significant correlation, suggesting a possible wave modulation by the 11-year solar cycle.
Dados de ventos obtidos entre 1999 e 2016 a partir de medidas por radar meteórico em Cachoeira Paulista (22,7°S, 45,0°O), Brasil, foram utilizados para investigar o comportamento da dinâmica da região da alta mesosfera e baixa termosfera, a variabilidade interanual dos ventos, das amplitudes da maré diurna e da onda de 2 dias e as possíveis causas. Os resultados mostram que o vento zonal é caracterizado por uma variação semianual abaixo de 90 km e anual acima, enquanto o vento meridional exibe um ciclo anual em todas as alturas. Os ventos mensais não mostraram variação quase bienal (QBO), contudo os ventos sazonais na direção zonal observados durante o verão e o outono mostram variações tipo QBO nas alturas abaixo de 90 km. Os resultados sugerem ainda que os ventos zonal e meridional são intensificados durante os anos de máxima atividade solar, principalmente nas estações de verão e inverno. As amplitudes mensais da maré diurna exibem variação interanual, em que as amplitudes são maiores durante a fase para leste da QBO em 30 hPa. O espectro obtido a partir das amplitudes dessazonalizadas mostra um pico próximo de 26 meses na componente meridional, o qual pode estar associado à fase da QBO estratosférica. A modulação da amplitude da maré diurna pela QBO mostra uma variação quase decenal, e é mais forte durante o máximo do ciclo solar. As amplitudes da onda de 2 dias exibem variabilidade interanual para ambas as componentes, contudo, apenas no inverno mostra ser afetada pela fase da QBO. Boa concordância entre a variação da amplitude meridional da onda de 2 dias e o fluxo de rádio solar foi observada para a maioria dos verões com correlação significativa, sugerindo uma possível modulação da onda pelo ciclo solar de 11 anos.
