摘　　要：为了对抗反舰导弹的威胁,箔条这种具有多种优点的无源干扰技术被越来越广泛的应用,因此对其进行识别和消除的工作变得相当重要,而小波通过对信号进行多尺度细化分析,能有效地从信号中提取信息,并能放大雷达回波信号的局部细节,从而实现对舰艇和箔条假目标的识别和区分,并进一步去除箔条干扰。利用小波分析这种新兴的信号处理技术中的Mallat算法,完成对箔条噪声消除的计算机仿真。As a good passive jamming technology, chaff gets widly used to against antiship missile. It becomes very important to recognize and remove it. While wavelet can make fractionized multiresolution analysis to the signal,so it can obtain the message from the signal effectively. And it can enlarge lacal details of radar echo signal, realize identifying the ship reflection and chaff cloud reflection to remove the chaff jamming. In the text we use new signal processing technology wavelet analysis Mallat algorithm to complete the computer simulation of chaff jamming removing.
