在分析毫米波雷达目标散射特性的基础上,提出一种基于小波变换的毫米波雷达目标识别方法。这种方法既保留了小波多分辨分析理论在分析高分辨雷达回波信号中的优点,又克服了小波变换没有时移不变性的缺点;同时对小波特征作了抗噪处理。目标识别对比实验获得了满意的结果,证实了这一方法的可行性。 Based on the analysis of the target scattering characteristics of millimeter-wave radar, a method of target recognition of millimeter-wave radar based on wavelet transform is proposed. This method not only retains the advantages of wavelet multi-resolution analysis theory in analyzing high-resolution radar echo signals, but also overcomes the shortcoming that wavelet transform has no time-invariant invariance. At the same time, the wavelet feature is denoised. The target recognition contrast experiment obtains satisfactory results, confirming the feasibility of this method.
