摘　　要：为了消除外界环境以及杂波和噪声对RCS测量精度的影响,提出了RCS测量数据的小波消噪方法,给出了小波消噪方法的具体步骤和实验结果。从实验结果可以看出,小波消噪方法能够对信号中的有用部分和噪声进行有效分离,使得信噪比及测量精度得到提高。The Morlet wavelet de-noising method of RCS data is introduced in order to eliminate the effect caused by environment and clutter data.The process and result of experiment are also presented.The result indicates that the new method can effectively separate useful components of the signal from noise.The SNR and measureme accuracy are increased correspondingly.
