Fast MUSIC method for enhancing radar angle resolution

The invention provides a rapid MUSIC method for enhancing radar angular resolution. The method comprises the following steps: step 1, establishing an equivalent array model of radar antennas, and then calculating the distance and direction between the antennas in the array; 2, constructing a spatial spectrum function, and estimating parameters of the signal through spectrum peak search; and 3, setting a transmitting array element to transmit # imgabs0 # chirp signals in one frame, so that a signal received by a single receiving array element in one frame is # imgabs1 #, and performing # imgabs2 # point sampling on the received signal to obtain maximum likelihood estimation of a finite-length data covariance matrix. According to the technical scheme, the estimation speed of the arrival angle of the target can be effectively increased, and the method can be applied to actual point cloud acquisition. 本发明提供了一种增强雷达角度分辨率的快速MUSIC方法，包括以下步骤：步骤一：建立雷达天线等效的阵列模型然后计算阵列中的各个天线之间的距离和方向；步骤二：构建空间谱函数，通过谱峰搜索，估计信号的参数；步骤三：设一个发射阵元一帧
