Embodiment Construction
[0071] The method of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0072] A radar radiation source identification method based on DCNN and Transformer, the specific implementation steps are as follows:
[0073] Training phase:
[0074] S1: Construct a data set, use MATLAB simulation to generate a data set of modulation type signals, including bi-phase coded signals, chirp continuous wave signals, Costas signals, Frank signals, polyphase codes (P1, P2, P3, P4) and multi-time codes ( T1, T2, T3, T4); the signal parameters are as follows:
[0075]
[0076]
[0077] Each modulation type signal generates 1000 sample signals under the signal-to-noise ratio of {-8dB, -6dB, -4dB, -2dB, 0dB, 2dB, 4dB, 6dB, 8dB} respectively, that is, each modulation signal generates a total of 9000 samples, a total of 108000 samples for twelve different modulation types. The ratio of the number of samples in various targe...
