DOA estimation algorithm of coherent sources for MIMO radar is presented by applying the diversity of the transmitted waveform and the symmetry of the transmitting and receiving array.The receiving data samples are reused to increase the number of samples
and obtain the receiving signal of transmitting and receiving virtual sub-arrays.The covariance matrixes of the virtual sub-arrays are derived utilizing the smoothing invariability and the DOA estimation precision is improved.Numerical examples are simulated to verify the effectiveness of the algorithm.
