Abstract

The inverse synthetic aperture radar (ISAR) imaging of non-uniformly rotating target and maneuvering target is a complicated task and the conventional range-Doppler (RD) ISAR technique does not work properly in this case. A novel ISAR technique, named range-instantaneous Doppler (RID), has been proposed to deal with this difficulty. In this paper, the fractional Fourier transform (FrFT) and the CLEAN technique are combined for RID imaging and the detailed algorithm is presented. We use computer simulation to demonstrate its performance and the simulation results show its effectiveness.
