本文主要应用DOA估计的子空间法多重信号分类算法(Multiple Signal Classification,MUSIC),对比分析了60元C60笼形规则阵列和随机分布阵列DOA估计的性能,旨在探讨设计具有高分辨率DOA估计性能阵列的可行性。仿真结果表明:在没有噪声的情况下,随机阵列DOA估计效果和规则阵列估计效果几乎没有区别,而在有噪声的情况下,随机阵列的DOA估计效果明显变差。
In this paper, the DOA estimation based subspace method MUSIC is applied to compare the performance of 60-DOF C60-Cail-like regular array and stochastic distributed array DOA estimation. The purpose of this paper is to discuss the design of high-resolution DOA estimation Feasibility of performance arrays. The simulation results show that there is almost no difference between the random array DOA estimation results and the regular array estimation results in the absence of noise. However, the performance of the random array DOA estimation is obviously deteriorated under noisy conditions.
