Abstract

The invention discloses a radar signal sorting method and device based on an improved cuckoo algorithm, and the method comprises the steps: obtaining a data object set, wherein the data object set is composed of N pulse description words of radar signals, and each pulse description word is composed of n-dimensional feature parameters; performing normalization processing on the data object set to obtain an intermediate set; performing isolated point removal processing on the intermediate set to obtain a target object set; and performing clustering processing on the target object set through an improved cuckoo algorithm and a K-means clustering algorithm, and outputting a clustering result. According to the invention, the improved cuckoo algorithm is introduced into the K-means clustering, the efficient local and global search capability of the improved cuckoo algorithm is utilized, the problems that the global search capability of the traditional K-means clustering is insufficient and is easy to fall into local optimum are solved, and the radar signal sorting stability is further improved.

Description

technical field [0001] The invention belongs to the technical field of radar signal processing, and in particular relates to a radar signal sorting method and device based on an improved cuckoo algorithm. Background technique [0002] With the continuous advancement of radar technology, new system radars emerge in endlessly. In modern electronic warfare, the number of radiation sources is increasing day by day, the modulation technology is becoming more and more complex, the frequency range of radiation sources is increasing, and the rapid development of precision guidance technology, all of which have great impact on Radar countermeasures put forward higher requirements. In modern electronic countermeasures, in order to effectively interfere with the opponent's radar signal, better obtain information, and gain the advantage of electronic warfare, it is necessary to implement sorting operations after receiving the enemy's radar signal. Signal sorting refers to the technolog...
