Research on Micro-Doppler Feature of Precession Target Based on Bistatic Radar

The micro-motion feature extracted form micro-Doppler is an important basis for target recognition in BMD. The micro-Doppler information in bistatic radar has many differences because of its spatial complexity compared with the monostatic radar. In this paper, micro-Doppler effect of precession warhead is derived in the bistatic radar system with LFM signals and the micro-Doppler signatures are analyzed. The micro-Doppler extracted from the echoes of warhead by means of time frequency representation is consistent with that of the theoretical value, which indicates the correctness and effectiveness of analysis in this paper.
