介绍了连续子波变换的定义和性质：基于子波变换在时域和频域的良好局部化性质；研究其在宽带信号的相关处理和超宽带雷达目标特征提取两个方面的应用，理论分析和试验结果表明，在超宽带雷达信号处理中，宽带相关处理相当于时间尺度域的匹配滤波，采用连续子波变换从频域采样数据中提取目标散射中心是一种较为鲁棒的方法。
The definition and properties of continuous wavelet transform are introduced. Based on the good localization of wavelet transform in time domain and frequency domain, the application of broadband wavelet transform in the correlation processing of broadband signals and the extraction of target features of UWB radar is studied. The theoretical analysis The experimental results show that the broadband correlation processing is equivalent to the time-domain matched filtering in UWB radar signal processing. It is a robust method to extract the target scattering centers from the sampled data using continuous wavelet transform.
