Performance Analysis of the Matrix Filter with Constant Stopband Constraint

在任意传感器阵型恒定阻带抑制矩阵滤波器设计的基础上,全面讨论了影响恒定阻带抑制矩阵滤波器性能的因素。矩阵滤波器设计问题可转化为二阶锥规划问题,通过求解二阶锥规划及重排可得所需的矩阵滤波器。分析并得出阻带响应、通带位置、通带带宽及阵元数等因素变化对矩阵滤波器性能的影响,为矩阵滤波器的设计和应用提供了依据。

This paper studied the factors which infect the performance of the matrix filter with constant stopband constraint on the bases of random array filter design. The design of matrix filter can be formulated into a second order convex programming. The required optimal matrix filter can be obtained by rearranging the solution of the second order convex programming The influence of the stopband attenuation, passband position, bandwidth and the sensor number to the performance of matrix filter are analyze＆ It gives warrant to the designation and application of matrix filter.
