为实现反辐射导弹分辨多个干扰源，根据空间谱估计原理，提出采用均匀圆形阵列天线结构对目标进行测向定位，并运用MUSIC算法估计其到达角，实现空域分辨。建立了基于均匀圆阵的二维DOA估计模型，讨论了角分辨算法在导引头中的具体应用。仿真结果证明了采用该方法能够有效分辨多个干扰源。

To antagonize multisources,the uniform circular array antenna was used in the anti-radiation missile （ARM） to locate the radar and baits according the principles of Space Spectrum Estimation,and the MUSIC was adopted to estimate the direction-of-arrival （DOA）. set the model of 2D-DOA estimation based on UCA, and discuss the implement of the algorithm in Passive Radar Seeker （PRS）; Computer simulation indicates that algorithm based on UCA can meet the need of angular resolution and resolute muhisources effectively.
