Abstract
Current sorting methods based on time difference of arrival (TDOA) can not concurrently realize the high sorting accuracy and low computational complexity with pulse loss and interference. This paper proposes a multi-station signal sorting method based on time difference pair and azimuth information. Firstly, the time difference window is introduced to determine the pulse range in which the pulse may be correctly matched with the pulse in the selected master station. According to the multi-parameters information, pulses in the range are accurately matched to get the real pulse pair and the time difference pair. Finally, the received signals are sorted by the time difference pair and azimuth information within the error tolerance. The simulation results show that the proposed method can effectively sort the interleaved signals with the pulse loss, interference, and the received pulses with few numbers. Furthermore, the computational complexity of the proposed method is greatly reduced.
