Analysing urban areas in the frame of non line of sight target detection. Electromagnetic modelling, validation and application to real data in Ka-band

ISBN: 978-1-4673-5705-0International audienceWe present in this communication our results on the study of urban canyons. This simple scene has been retained to produce a first analysis on urban areas, as the canyon can be seen as one canonical structure inside cities. Our initial goal was to determine if a stationary target can be detected within a canyon in a non-line of sight configuration. Our strategy was to develop simple but fast algorithms to study such configurations and to complete these codes with a commercial software in order to further analyze the absolute amplitude of the backscattered fields. These codes have been applied on real SAR and INSAR data acquired by ONERA over industrial areas at Ka-band
