摘要：

In this paper, we combine the concepts of evolutionary spectrum and array processing and sent a high-speed method to estimate the direction-of-arrival (DOA) of nonstationary signals with the theories of cross-power evolutionary periodogram (CEP) and beamforming. The proposed method implements three-step DOA estimation. First, we estimate the cross-power evolutionary of the sensor array using the minimizing mean-squared error. Second, estimate the DOA using the beamspace MUSIC method roughly. And last, accurately estimate the DOA with the result of coarse estimation.
