Angle estimation of coherent multi-target for MIMO bistatic radar

The angle estimation algorithm of coherent multi-target for MIMO bistatic radar is presented. In the algorithm, the virtual array data from multi-target in MIMO receiver is firstly decorrelated, then special matrix based on the ESPRIT method is constructed, finally the eigenvalues and the eigenvectors of the matrix are used to estimate direction of departures and direction of arrivals. In this algorithm, the parameters can be directly paired by the relationship between the eigenvalues and eigenvectors. The correctness and performance of the proposed method are verified by the computer simulation.
