| 摘 要： | 小波变换具有良好的时频特性和多尺度分析能力，因此在信号分析中得到了越来越广泛的运用。文章就信号去噪的小波变换在多普勒雷达测速系统中的应用进行了分析，并对此系统中运用阈值去噪法时阈值选择的不足进行了改进，取得更好的去噪效果，最后通过仿真进行验证，证明改进方法简单有效。

| Abstract: | The wavelet transform has good time-frequency characteristics and multi-scale analysis capabilities,and has been widely used in signal analysis.This paper takes signal denoising wavelet transform in speed radar system with Doppler analyzing and use less than the selected threshold when the threshold denoising method improved in this system,to achieve better denoising effect,and finally verified by simulation to prove that the improved method is simple and effective. |

| Keywords: | wavelet transform speed radar signal denoising threshold selection |
