摘要 分析了圆阵列MUSIC算法二维测向的原理。圆阵列MUSIC算法分辨性能与多种因素有关。定义两种衡量分辨性能的参数,即分辨力和可分辨概率,并给出计算方法。两种参数均需要从方位角和俯仰角两方面考虑。仿真实验证明本文分析方法是有效的,同时得到分辨性能与快拍数、信噪比(SNR)等因素之间的变化规律。 The 2D direction-finding principle of the circular array MUSIC algorithm is analyzed.The resolution performances of the circular array MUSIC algorithm are related to several factors.The resolution parameters,namely,the resolution and the resolvable probability,are defined to evaluate the resolution performances with the calculation methods given.Both of the parameters are required to take the azimuth and the elevation angles into consideration.The simulation results indicate that the methods are effective,and the variation relationships between the resolution performances and the snaps and the SNR are obtained at the same time.
