The existing deinterleaving algorithms have some problems such as difficulty in sorting complex modulation signals

high false alarm or false dismissal rate

poor performance on low repetition frequency signals

and poor real-time performance. In order to solve the above problems

this paper proposes a real-time single pulse signal sorting method based on multi-stations time difference of arrival (TDOA) and multi-parameters information. Firstly

the time difference window is introduced to make rough pairing of pulse signals received by multi-stations to obtain multiple "pulse pair" sequences which may be correctly paired. Then

the "pulse pair" is accurately matched by intra-pulse parameters to obtain the true "pulse pair". Then

the time difference corresponding to the "pulse pair" is calculated and the "time difference pair" sequences are obtained. Finally

within the error tolerance

according to the invariance of time difference

the single pulse signal is sorted in real-time. The simulation results show that compared with the existing algorithms

the algorithm can effectively sort complex inter-pulse or intra-pulse modulated signals and low repetitive frequency signals

with extremely low false alarm

false dismissal rate and high correct sorting rate. At the same time

it is real-time.
