摘要
分析了宽带干扰对旁瓣对消系统的影响,介绍了相关系数的计算方法,并给出宽带干扰下按最小均方(LMS)准则求解加权系数的计算过程,然后以天线阵对干扰的方向增益为依据,借助于Matlab给出宽带干扰的效果分析。
This paper analyzes the influence of wide-band jamming to the side-lobe cancellation system,introduces the method to calculate the correlative coefficient,and gives the process in term of least mean square（LMS） rule to calculate the weighting coefficient under the wide-band jamming,then according to the direction gain of antenna array to the jamming,presents the effect analysis of wide-band jamming through Matlab.
