| 摘 要： | 阵列误差会使MUSIC算法的性能急剧下降.现今大多数校正算法都是用于校正方位无关的阵列误差.但实际中的阵列误差几乎都与信号方位有关.辅助阵元法是校正方位相关阵列误差的有效方法.首先论述了辅助阵元法与MUSIC算法相结合的算法,然后重点分析了信噪比和校正阵元的精度对算法性能的影响,同时提出了提高算法精度的方法,为实际应用提供参考.仿真实验验证了算法的有效性.

| Abstract: | The performance of MUSIC algorithm will decline seriously by the array errors.Today,most array error calibration algorithms are used to calibrate direction-irrelevant array errors.However,array errors are almost direction related in practice.Instrumental Sensors Method is an effective algorithm for direction-relevant array error calibration.Firstly,this paper discusses the algorithm which combines Instrumental Sensors Method with MUSIC algorithm,and then analyses the impact of SNR and instrumental sensor ac... |
