摘　　要：在基于阵列信号处理技术的卫星导航接收系统中,当卫星信号的估计导向矢量与真实导向矢量失配时,常规的干扰抑制算法将有较大的性能损失。将导向矢量旋转法引入到多级维纳滤波器中(CSA-MWF),该方法在提高系统稳健性的同时,有效降低了计算量。计算机仿真表明,小快拍条件下新算法的干扰抑制性能优于导向矢量旋转法。Traditional adaptive array processing suffers performance degradation in the presence of mismatch between the actual and presumed array steering vectors in satellite navigation systems.The steering vector rotation technique is introduced to the multistage wiener filter(MWF).The proposed approach improves robustness and reduces the computation complexity obviously.Simulation results demonstrate its superiority in low sample support environments.
