Abstract

The micro-Doppler signature of a target can provide more information for target classification and recognition. Battlefield surveillance radar has low Doppler resolution, which provide coarse micro-Doppler signature. In order to get more detailed micro-Doppler signature, high-resolution time-frequency distribution is necessary. In this paper, we use S-Wigner distribution(SWD), compared with STFT, to analysis the micro-Doppler signature of vibratory and three typical ground targets in battlefield.
