Abstract

In the bistatic radar using broadcasting signals, the delays between signals propagated directly and scattered by the target are measured to estimate the target position with cross-correlation. This results in the delay profile with the width limited by the bandwidth of the signal. To get better resolution, larger bandwidth is required, however, the bandwidth of broadcasting signals can not be increased by the receiver. In this paper, we propose a new method of the moving target detection with MUSIC (MUltiple SIgnal Classification), processed at only receiver. That offers much narrower width than that of cross-correlation. The proposed method can distinguish the moving targets from the stationary targts, though the conventional MUSIC can not. This is realized by the decorrelation of the time delay-derived phase rotation factors caused by moving targets. The performances using ISDB-T(Integrated Service Digital Broadcasting - Terrestrial), the bandwidth of which is 5.57MHz, are evaluated by the computer simulations. The results show that two close moving targets, separated by 0.1μs, with SNR=-10dB each can be resolved even if the stationary target is located around the one moving target.
