摘　　要：基于信号脉内调制信息识别技术对密集和复杂环境中辐射源的分选和识别的重要性.研究了基于小波多分辨分析技术识别相位编码(PCM)信号的脉内调制信息的算法,分别运用计算机仿真数据和专用设备提供的仿真数据进行了算法验证,结果证实了该算法的可行性.The in-pulse modulation feature is crucial for the classification and recognition of radiants in highly dense and complex environment. Based on the wavelet multi-resolution analysis, the identification method of in-pulse modulation feature of phase coding signal is proposed in the paper. Furthermore, the efficiency of the method is proved by both the computer simulation data and the special-device simulation radar IF data.
