Stepped-frequency pulses achieved large bandwidth using a group of pulses, thus avoiding overlarge instantaneous bandwidth of traditional radar with high resolution. It played an important part in decreasing instantaneous bandwidth and requirement to the receiver. This study aimed at analyzing all steps of stepped-frequency pulse processing and non-coherent factors for compensation. Meanwhile, it...
Multiple targets imaging using inverse synthetic aperture technique is a key problem on radar imaging field. This paper proposes a new approach to perform the motion compensation for multiple targets using randomized Hough transform (RHT). The targets' amplitude distribution, i.e., corrugation image is transformed into frequency domain, then The RHT processing is operated on the frequency image to...
