Abstract In general, the method of conventional motion compensation for inverse synthetic aperture radar (ISAR) imaging is divided into translational motion compensation (TMC) and rotational motion compensation (RMC) in sequence. TMC is the premise o

Inverse synthetic aperture radar (ISAR) imaging for noncooperative targets with complex translational motion (TM) and 3-D rotational motion (RM) face the problem of spatial-variant (SV) and high-order phase modulation. The existing ISAR technique can
