A multi-look fusion approach to through-wall radar imaging

Through-wall radar imaging using ultrawideband signals is of interest for mapping interior room layouts of buildings, for detection of targets concealed within buildings and for determining in-wall structure. In this paper, we present some experimental results that demonstrate the benefits of a multi-look fusion approach for both interior room mapping and concealed target detection. In particular, we describe a concept of operation that requires only a single data collection pass in front of a building of interest, where the multiple looks are derived from images processed with different squint angles.
