Abstract

The invention provides a radar pulse repetition frequency sorting method and equipment, the main purpose of which is to solve the problem of radar pulse sorting in complex environments in the prior art. The technical solution of the present invention is: obtain the pulse description word PDW of the received pulse, perform pulse repetition interval PRI conversion according to the arrival time TOA in the PDW, and obtain the PRI spectrogram; search for the peak in the PRI spectrogram, and identify the The PRI value corresponding to the peak value; the TOA corresponding to the first pulse received by all pulses is subtracted to obtain the time difference of arrival DTOA of the pulse train, and a two-dimensional plane is generated according to the DTOA and the PRI value, Marking the pixel points corresponding to the pulse amplitude PA, carrier frequency RF, and pulse width PW of the PDW; determining a plurality of straight lines corresponding to the pixel points; fitting the straight lines, and fitting the straight lines corresponding to the fitting results A pulse is determined as the sorting result.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a radar pulse repetition frequency sorting method and device. Background technique [0002] In the process of electronic reconnaissance, in order to distinguish the pulse signal received in the reconnaissance system from the pulse signal belonging to the same radiation source, so as to identify the radiation source and process the pulse signal, sorting the pulse signal has become the key step. Among them, the sorting of radar pulse signals should firstly use the pulse amplitude PA, carrier frequency RF, pulse width PW, and angle of arrival DOA for simple pre-sorting, and then perform pulse deinterleaving main sorting with pulse repetition interval PRI. [0003] For the pre-sorting process, the first thing is to calculate and compare each pulse description word PDW in the input pulse stream with the relevant radiation source file parameters pr...
