In this paper, a combined OFDM system and bandpass sampling method using Multiple Signal Classification(MUSIC) algorithm for automatic (angle of arrival) AOA tracking is discussed. And we propose a new method that adding (time division multiplexing)TDM with bandpass sampling in the same time to avoid interference due to RF filter characteristics. Also, we consider Doppler effect for the targets’ movement and after compensating the Doppler effect with a valid range , the system performances well. Computer simulation shows that the performances of MUSIC spectrum for AOA due to various conditions and demonstrates the accuracy of AOA estimations.
