Pulse Sorting Algorithm Using TDOA in Multiple Sensors System
Shuang Ma, Zheng Liu, Wen Li Jiang · Advanced materials research · 2012
Time difference of arrival (TDOA) can be used for pulse sorting. To solve the problem of deceptive TDOA clusters caused by high pulse repetitive frequency (PRF) emitters and the problem of less pulse accumulation caused by ultra-low PRF emitters, a recursive extended histogram (REH) algorithm is proposed. TDOA data are formed into an extended histogram structure, which is processed recursively to detect and sort out the pulses of each emitter. Simulation results show that the method is applicable and effective.
