摘　　要：针对多级维纳滤波器在降维和计算复杂度低方面的突出特点,对多级维纳滤波器在采样率对其滤波性能影响方面进行进一步研究。通过理论推导得到了输出功率比率期望误差与采样率之间的关系公式。计算机仿真验证了多级维纳滤波器在波达方向估计时此公式的正确性。According to the outstanding performance in rank reduction and low computational complexity, a further research carried on the performance of multistage - Wiener - filter in the influenced aspect of sample rate. Through the theoretics derivation we get the formula of the expected loss in power ratio and the sample rate. Simulation shows the formula is correct in estimation of direction of arrival via multistage - Wiener-- filter.
