摘要
提出了一种基于双基地多输入多输出(MIMO)雷达的快速目标空间定位算法。该算法通过双基地MIMO雷达单周期回波形成的虚拟阵列数据来构造三个矩阵,然后用传播算子法分别对其进行处理得到了三个具有特定关系的矩阵,利用矩阵的特征值和特征向量导出了目标角度的闭式解,从而可实现对目标的空间定位。该算法避免了数据协方差矩阵的估计,不需要多维谱峰搜索和参数配对,大大降低了运算复杂度。计算机仿真结果证明了所提算法的正确性和可行性。
Based on bistatic multiple input and multiple outp at（MIMO） radar, a fast spatial target localization algorithm is proposed. The algorithm uses the data of the virtual arrays formed by bistatic MIMO radar to construct three matrices, and three matrices with designated relationship are obtained through the propagator method. Finally, the closed-form solution of the angles is obtained by the eigenval- ues and the eigenvectors of the matrices, so the spatial localization for targets can be realized. The proposed algorithm avoids the estimation of the covariance matrix, and does not need multi-dimensional spectrum peak searching, thus the computa- tional complexity of the algorithm is reduced. The correction and efficiency of the proposed method are verified by the computer simulation results.
