Abstract

Based on 2-D discrete fourier transform

the principle of ISAR(Inverse Synthetic Aperture Radar) imaging and its doppler effect are analyzed for stepped frequency waveform.Phase match processing technology is proposed to achieve ISAR image of target with micro-motion.The new technology has an innovative physical interpretation.Monte Carlo simulations with synthetic data demonstrate the performance of the new technology.The results confirm the ability of the new technology to reconstruct the ISAR image of a target with micro-motion.
