摘要：在连续波干扰和脉冲干扰同时存在时，卫星导航接收机的调零天线如果采用经典LMS算法计算权矢量，存在收敛速度慢，对脉冲干扰抑制能力有限的问题.在对脉冲进行有效检测基础上，针对脉冲存在和不存在两种情况下的不同信号特征，采用两路并行权值计算模式，最后根据脉冲信号的有无选择输出权值.理论分析和计算机仿真结果表明，与经典LMS算法相比，新方法收敛速度快，可以对脉冲干扰进行有效抑制.

Abstract: When the continuous wave interference and impulse interference presence at the same time for the satellite navigation receiver, the nulling antenna will face the problem of low convergence speed and limited suppression performance to impulse interference assuming the classical LMS algorithm is taken to calculate the weight vector. A new strategy with two parallel calculations for weight vector is proposed according to the various signal characteristics on the condition that we can detect the impulse interference correctly. The new method choose only one weight vector from the two results as the last output of the antenna according whether the impulse interference exits. The theoretic analysis and computer simulation illustrate that the proposed approach could obtain a faster convergence speed and better suppression to the impulse interference compared with the classical LMS algorithm.
