A target is assumed to be of a finite size with multiple high-lights instead of just a "point". An array signal model of echoes from multiple high-lights of the target is established. A beam transformation matrix is defined to convert the signals from the elementspace to the beamspace. Then the MUSIC algorithm is used to estimate the direction of arrival (DOA) for the multiple high-lights. The resolution probability and the mean square error of the estimates of the B-MUSIC based on different SNRs and different broad angles are statistically analyzed by simulations. The results show that the proposed algorithm enjoys high angular resolution and good precision in the condition that the sonar is located near the vertical direction to the target broadside or the SNRs is high., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=JIA Ji-Peng, copyrightStatement=null, copyrightOwner=null, extLink=null,

articleAbstract=对基于目标多亮点的波束域MUSIC算法进行了研究。把目标不再看成为一个点目标，而是看成有一定尺度大小的多亮点目标。首先建立了尺度目标多亮点的回波信号模型，再通过设计波束转换矩阵将阵元域信号转换到波束域，然后对波束域信号应用MUSIC算法估计目标亮点的方位，并在不同信噪比和不同敌舷角条件下对波束域MUSIC方法方位估计的分辨概率和均方误差进行统计分析。仿真结果表明，当声纳位于目标正横方向附近时或在高信噪比条件下，波束域MUSIC方法具有很高的方位分辨能力和估计精度。,
