【Abstract】 Imaging of moving targets by inverse synthetic aperture radar (1SAR) is based on range-Doppler processing and motion compensation. High resolution along the range is provided by broad bandwidth of the transmitted signal, while accross the range (azimuth) provided by an aperture induced by the motion of the target. Range alignment and motion compensation are the key techniques of ISAR. ISAR principles are summarized and experimental results are given.更多还原
