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...
Based on compressive sensing theory, a new method for high resolution inverse aperture radar (ISAR) imaging of maneuvering target is proposed. In this method, only a few measurements in ambiguity function plane are sampled to reconstruct the time-frequency distribution by solving the inverse problem using basis pursuit method. With a Gaussian window as a sampling function, the trade-off between the...
