Abstract A new blind beamforming algorithm for multitargets is presented in this paper. This method can estimate the weights of beamformers blindly by minimizing a new cost function based on least-squares constant modulus algorithm so as to separate the multitargets and find the direction. At the same time, a developed neural network is used to compute the inverse of a matrix, which not only improve the computing speed but also use easily hardware to carry out the blind beamforming. Simulation proves correctness of this algorithm.
