A Study on Multi-plane Passive Location Algorithm Based on TDOA Sequence

Multi-plane passive location based on TDOA sequence is a method of locating impulse radiation sources,using plenty of TDOA information to locate the target in a very short time.Based on TDOA sequence,two practical multi-plane passive location algorithms are proposed.During the short time of the target's pulse beam scanning the flight team,the positions of planes are approximately regarded as constants,so that two-step WLS algorithm can be used to locate the target instantly.ML algorithm could be used to improve the accuracy of location in the condition of low TDOA measurement accuracy.Simulation results show that the algorithms proposed can achieve high location accuracy,which means good utility value.
