摘要
在非均匀线阵上应用MUSIC算法进行测向.阵列模型采用最小冗余阵列,排除了测向模糊的影响.本文通过仿真,分析了信噪比、快拍数、阵元数等因素对MUSIC算法的影响,同时表明,非均匀阵列的测向分辨率精度高于均匀阵列的分辨率精度.
MUSIC algorithm is used to estimate the Direction-of-Arrival(DOA) in non-uniform arrays.To achieve unambiguous DOA estimation,the minimum-redundant linear array is applied to the array model.Through the simulation,the influence of SNR,number of snapshots and array elements on MUSIC,is analyzed and the result proves that higher resolution can be achieved in the non-uniform arrays.
