Multitarget Localization in Three Dimensions for MIMO Bistatic Radar
MIMO双基地雷达空间多目标定位方法

A novel method of multitarget localization in L shaped MIMO bistatic radar is proposed. Based on four angles information involved in L shaped receiving array from target to transmiter and receiver, the joint estimation algorithm for four angles of multitarget can be obtained by the following steps: uncorrelating the array data of received echoes first, then constructing estimation matrix based on the DOA matrix method, finally using the given relationship between the eigenvalue and the estimated parameters. As a result, the multitarget localization in three dimensions is achieved in the bistatic radar. The proposed algorithm does not refer to multi-dimensional nonlinear peak search, and need only once eigenvalue decomposition, so that the computed load of the algorithm is low, and the estimated parameters of the targets can be paired automatically. The correctness and effectiveness of the proposed method are verified with the computer simulation.
