摘　　要：根据机械扫描雷达、一维相控阵雷达和二维相控阵雷达扫描方式的差异,通过对3种体制雷达进行双谱分析、切片化处理以及小波包分解,提出了双谱切片小波包的概念,并根据此特征用支持向量机对不同体制的雷达进行识别。仿真结果表明:该方法在噪声占比为0~20%时,可分性好,并且在噪声占比增大时,通过该特征仍能对不同体制的雷达进行有效识别。According to the difference of scanning methods among mechanical scanning radar,onedimensional phased array radar and two-dimensional phased array radar,based on the bispectrum analysis,slicing and wavelet packet decomposition of the three radar systems,the features of the bispectrum slice wavelet packet are obtained,and the radar signal is identified by supporting vector machine(SVM).Simulation results show that the method in this paper has good separability when the percentage of noise is 0~20%,and can still effectively identify radar systems through this feature when the percentage of noise increases.
