摘要
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 wavelet transform has favorable localization character in time domain and frequency domain, which is specially applicable in wideband signal. In this paper, the applications in wideband correlation processing and target feature extraction are stlldied. Theoretic analysis and experimental results show that the continuous wavelet transform is an effect approach in ultra-wideband radar signal processing.
