摘要 为了实现双基地多输入多输出(MIMO)雷达目标参数估计,建立了双基地MIMO雷达信号模型,提出了一种目标方向角和多普勒频率联合估计的方法,该方法通过构造空时矩阵,只进行一次特征值分解,即可得到雷达多目标多参数的闭式解,避免了多维非线性的谱峰搜索,并可实现自动配对。仿真结果证明了所提算法的有效性。 A signal model of the bistatic MIMO radar for target parameters estimation is set up, and a joint angle and Doppler frequency estimation al- gorithm is proposed. By defining a space-time matrix, the proposed method can get closed-form solutions of the multi-targets parameters using eigenval- ue decomposition only once, and avoid the multi-dimensional nonlinear peak search. In addition, the pairing of the parameters is automatically obtained. The simulation results show the effectiveness of the proposed algorithm.
