Problems solved by technology

However, for new radar signals, due to the inability to use prior knowledge, the identification cost of reconnaissance aircraft is high, making it difficult to obtain more samples of new radar signals. The recognition rate of traditional recognition methods is low, and the recognition takes a long time

Abstract

The invention relates to a radar signal sorting identification method and device, a detector and a readable storage medium, and the method comprises the steps: processing a target radiation source signal through employing a CWD time-frequency analysis technology and a short-time autocorrelation feature image construction method, and obtaining an original time-frequency image and an autocorrelationfeature image; and obtaining a classification result through a convolutional neural network feature extractor and a random forest classifier, and after the classification result is subjected to weighted fusion, obtaining a sorting identification result, so that the technical problem of relatively low accuracy of identifying unknown radar waveforms by using a CWD time-frequency analysis technologyin the prior art is solved And the recognition rate of unknown radar signals is greatly improved by only using less radar sample information.

Description

technical field [0001] The invention relates to the technical field of radar signal identification, in particular to a radar signal sorting and identification method, device, detector and storage medium. Background technique [0002] In modern electronic warfare, the analysis and processing of radar emitter signal is one of the important links of electronic intelligence reconnaissance system and electronic support system. Radar signal styles are complex and have many working modes. Especially in wartime, new radar signals are constantly emerging. For some radar waveforms with known modulation methods, the correlation between the radar prior knowledge and the radar signal received by the reconnaissance receiver can be used. Identify categories. However, for new radar signals, due to the inability to use prior knowledge, the identification cost of reconnaissance aircraft is high, making it difficult to obtain more samples of new radar signals. The recognition rate of traditi...
