Abstract

The invention discloses a radar signal sorting method and device based on an improved cuckoo algorithm. The method includes: acquiring a data object set, the data object set is composed of N pulse description words of radar signals, and each pulse description word It consists of n-dimensional feature parameters; normalize the data object set to obtain the intermediate set; remove outliers from the intermediate set to obtain the target object set; improve the cuckoo algorithm and K-means clustering algorithm to obtain the target object set. The object collection is clustered and the clustering result is output. The invention introduces the improved cuckoo algorithm into K-means clustering, utilizes the improved local and global search ability of the improved cuckoo algorithm, and solves the problem that the traditional K-means clustering has insufficient global search ability and is easy to fall into local optimum, Thus, the stability of radar signal sorting is 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 progress of radar technology, new radar systems emerge in an endless stream. In modern electronic warfare, the number of radiation sources is increasing, 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. Radar countermeasures put forward higher requirements. In modern electronic countermeasures, in order to achieve effective interference to the opponent's radar signal, better obtain information, and obtain electronic warfare advantages, it is necessary to implement the sorting operation after receiving the enemy's radar signal. Signal sorting is a technology that separates all the pulse sequences of...
