Abstract
The micro-motion characteristics and micro-Doppler of ballistic targets are becoming a research hotspot in target recognition domain. In this paper, micro-motions of ballistic targets are analyzed, and the methods of extracting micro-Doppler of narrowband and wideband signal are studied. The autocorrelation in time domain and cepstrum in frequency domain are introduced to extract the period of micro-Doppler variation. The experiment to extract the micro-Doppler of warhead in darkroom is carried out. The experimental result proves that the methods proposed above are valid.
