Abstract
High-resolution microwave imaging of moving targets can be achieved by inverse synthetic aperture radar (ISAR). Information processing of ISAR, including motion compensation and image-formation, is investigated by use of the real data of a Boeing-727 commercial aircraft. Several motion compensation schemes for ISAR are formularized and compared. A superresolution imaging method based on data extrapolation is carried out enhance image resolution. The reconstructed images of a Boeing-727 are given. This demonstrates the correctness and effectiveness of the motion compensation and superresolution approaches which are discussed. >
