Embodiment 1

[0072] Embodiment 1: Assuming that 5 inter-pulse collections of a certain type of radar emitter signal are collected, each inter-pulse collection includes several inter-pulse signal measurement values, the unit is microseconds (us), and the length of each inter-pulse collection ranges from 2 From small to large, the pulse intervals are sorted from small to large, and the high-frequency pulse intervals of this type of radar emitter signal are analyzed and mined. The five pulse intervals are shown in Table 1.

Abstract

The invention discloses a radar radiation source pulse-to-pulse mode excavation method based on fuzzy matching. According to the radar radiation source pulse-to-pulse mode excavation method based on fuzzy matching, the degree of fuzzy matching between every two radar radiation source pulse-to-pulse sets of a certain radar radiation source is measured through setting of pulse-to-pulse similarity threshold delta values, and then the pulse-to-pulse sets with the fuzzy matching frequency larger than or equal to a support degree threshold thresh value are further excavated. The radar radiation source pulse-to-pulse mode excavation method based on fuzzy matching has the advantages that a novel analysis method for the radar radiation source pulse-to-pulse signal sequence is provided, and analysis is not limited by radar radiation source pulse-to-pulse signal individual analysis; the type of radar radiation sources with superposed radar radiation source pulse-to-pulse signal feature distribution ranges and different pulse-to-pulse sets can be conveniently distinguished; the calculation cost is low, the implementation method is engineered, and the excavated pulse-to-pulse sets can effectively improve the analysis and handling capacity for the radar radiation source pulse-to-pulse signal sequence.

Description

technical field [0001] The invention relates to the field of data analysis and processing for radar radiation source identification, in particular to a fuzzy matching-based mining method for radar radiation source interpulse patterns. Background technique [0002] As we all know, the signal overlap of different types of radar emitters is getting higher and higher. In terms of pulse-to-pulse signals, it is possible that the distribution ranges of pulse-to-pulse signals from different types of radar emitters are relatively similar, and in addition to traditional continuous signals and discrete signals In addition, there are interpulse collection signals. Although a variety of radar emitter signal analysis methods have been proposed in academia, these methods are mainly limited to single-valued pulse-to-pulse signal analysis, and it is difficult to effectively distinguish different types of radar emitters whose pulse-to-pulse signal ranges overlap. [0003] The current radar e...
