The problem of inverse synthetic aperture radar (ISAR) image reconstruction of targets in short-range is considered. In this geometric condition the main causes affecting the reconstructed ISAR image are: non-uniform planar rotation with a time varying angular velocity and different angular rotation rates of the scatters on a target. Based on the analysis of motion characteristics of the moving target, several techniques are discussed for achieving the ISAR image for targets in short-range.
