Abstract

The invention is applicable to the field of computers, and provides a radar radiation source identification method. The radar radiation source identification method comprises steps: to-be-identified radar radiation source signals are received; the to-be-identified radar radiation source signals are subjected to wavelet transformation to generate a two-dimensional wavelet matrix; the two-dimensional wavelet matrix is processed to generate a time-frequency domain gray image; and a radar radiation source corresponding to the time-frequency domain gray image is determined according to the time-frequency domain gray image and a radar radiation source identification model generated and trained based on a convolutional neural network algorithm. According to the radar radiation source identification method provided in the embodiment of the invention, the to-be-identified radar radiation source signals are subjected to wavelet transformation and are then processed to be the time-frequency domain gray image, the radar radiation source identification model generated and trained based on the convolutional neural network algorithm is used, the radar radiation source can be directly determined,and in comparison with the existing identification method, the data processing amount can be effectively reduced, the processing efficiency is improved, and the identification accuracy is good.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a radar radiation source identification method, device, computer equipment and storage medium. Background technique [0002] With the development of science and technology, radar is also more used in the military and aviation fields. Especially in the military field, radar can effectively detect the military situation, and can effectively take the lead in the military. Correspondingly, radar interference and radar recognition performance have become an important indicator to measure radar performance. [0003] In the prior art, radar often needs to process the received signal containing noise, and then identify the processed signal, so as to identify the corresponding radar radiation source. However, in the prior art, the short-time Fourier transform is generally used to process the signal, and the signal needs to be pre-processed for noise reduction before that, the process...
