Siliang Wu · Modern Radar · 2007
In this paper a space location algorithm for moving point scatter based on impulse radar is presented. According to the characteristic of impulse radar, this algorithm collects return signal by equivalent sampling using range gates. Then measure the distance differences of every range gate between the different receiving antennas by correlating of the collected data. The TDOA method can realize the localization on every range gate of referenced receiving antenna. Futher the kalman smoothing filter is adopted to obtain a more accurate localization result by constructing target moving model. Simulation results show that the algorithm can get satisfacting space localization accuracy.
