Aiming at the signals sorting problem, a joint sorting algorithm based on direction finding of multiple observation and multi-parameter information is proposed based on the condition of multiple observers receiving the emitter pulse signals. Firstly, benchmark pulse is determined in the pulse stream of master observation platform, and matching pulse is searched by multi-parameter information in the pulse stream of slave observation platforms. Then the pulses maybe from the same emitters are searched through location and multi-parameter information in the master observation platform, and the pulses
matching with the master observation platform in slave observation platforms are searched. Finally, matching pulses in the master observation platform are extracted. Experimental results show that, when the number of pulses observation platforms received is less and sorting algorithms based on the PRI statistical rule are no longer applicable, pulse sequences can still be sorted with high accuracy rate by using the proposed algorithm.
