Smart antenna can improve the capacity and anti-jamming performance of DS/CDMA system, but some approach of DOA estimation can’t be calculated in real time because of complexity of calculation. Two low complexity approach of DOA tracking estimation are studied in this paper, a new improved fast approach of DOA tracking estimation is presented based on double beam and changeable step, the simulation results reveal that the resolution of DOA estimation is higher than the other two approaches in evidence, furthermore, its computation complexity don’t increase significantly.
