Abstract

The invention relates to a radar radiation source signal classification and identification method adopting an ICGAN and ResNet network, and the method comprises the following steps: 1, receiving aliasing signals through a receiver, separating the aliasing signals, and generating six common radar radiation source signal data sets, and 2, carrying out a signal preprocessing method; 3, constructing an ICGAN, 4, constructing a deep residual network (ResNet), and 5, inputting the test set sample into the ResNet, and outputting a recognition result of radar radiation source signal classification. The method aims to extract different types of radar radiation source signal features under the condition that the number of samples is insufficient, the number of the samples is expanded by utilizing ICGAN, and then the types of the radar radiation source signals are accurately distinguished by utilizing ResNet; the method not only can solve the problem that the number of samples is insufficient, but also can improve the recognition rate of different types of radar radiation source signals.

Description

technical field

[0001] The invention belongs to the technical field of digital communication, and in particular relates to a method for classifying and identifying radar radiation source signals using ICGAN and ResNet networks. Background technique

[0002] As an important part of electronic technology reconnaissance, the identification of radar emitters has always been a hot research topic in the field of communication countermeasures. Its main process is: measure the radiation source signal received by the receiver, analyze and process it, and identify the individual radar radiation source according to the existing prior information. The traditional signal analysis method is mainly realized through the analysis of conventional parameters such as pulse width and carrier frequency, and then matching the corresponding template. Under the situation of continuous development of radar technology and the development of electromagnetic environment, it has been unable to achieve hi...
