Zusammenfassung:	The invention provides a radar active interference identification method based on CWD and improved AlexNet. The radar active interference identification method is used for identifying radar active interference signals in communication signals. The method comprises the following steps: firstly, modeling different types of radar active interference signals, and superposing noise of a communication signal receiving site on the various radar active interference signals; performing CWD time-frequency analysis on the various radar active interference signals to generate a two-dimensional CWD time-frequency graph; and an improved AlexNet model is adopted to identify the CWD time-frequency diagrams of the various radar active interference signals. According to the radar active interference identification method based on the CWD and the improved AlexNet, an interference identification algorithm combining a CWD time-frequency analysis method and an improved AlexNet model is adopted, the characteristics of radar interfe
