摘要
分析了雷达回波信号中所含噪声的特点、小波变换的原理 ,在此基础上着重论述了小波变换应用于雷达回波信号消噪处理的原理和方法 ,并从仿真试验中验证 :将小波变换应用于雷达回波信号的消噪处理 ,可以极大地改善回波的信噪比 。
Based on analyzing the characteristic of the noise in the radar echo signal and the principle of the wavelet transform, this article discusses the principle and the methods of applying the wavelet transform in restraining noise of the radar echo signal . From imitating experiments we conclude : utilizing these methods ,we can improve the signal-to-noise rate(SNR) and the detection probability of the echo signal.
