I. Introduction
In Electronic warfare, to obtain information about a target radar, it is necessary to use electronic reconnaissance equipment for reconnaissance and interception of the corresponding target radar signal. The process involves detection of signals first [1], [2]. and then analysis of the detected signals In an actual electromagnetic environment, there are often other electromagnetic signals besides the target radar signal. In that case, data collected by electronic reconnaissance equipment may contain information from different targets, and the intercepted pulse stream may also contain interleaved pulses from different radiation sources, as shown in Fig. 1. Full pulse data (FPD) are pulse description words for each pulse output in chronological order in electronic reconnaissance equipment. Pulse description words include the time of arrival (TOA), direction of arrival (DOA), pulse width (PW), radio frequency (RF), pulse amplitude (PA), and other information about each pulse. Radar signal deinterleaving, which is an important part of electronic reconnaissance, is essentially to deinterleave the interleaved pulse description words belonging to different radiation sources in the FPD.
