Detection and localization of stationary targets behind walls is primarily challenged by the presence of the overwhelming EM signature of the front wall in the radar returns. In this paper, we address suppression of front wall clutter prior to image reconstruction for a stepped-frequency radar imaging system, when different sets of few frequency observations are available at different antennas in...
Compressive sensing (CS) for urban operations and through-the-wall radar imaging has been shown to be successful in fast data acquisition and moving target localizations. The research in this area thus far has assumed effective removal of wall electromagnetic backscatterings prior to CS application. Wall clutter mitigation can be achieved using full data volume which is, however, in contradiction...
