将MIMO思想和双基地雷达结合起来,根据信号模型,提出一种双基地MIMO雷达空间中的多目标角度和多普勒频率估计算法,该算法不涉及多维非线性谱峰搜索,只进行特征值分解,运算量小且估计的参数可以自动配对,理论分析及仿真实验结果表明了该方法的正确性和可行性。

Combining MIMO idea with bistatic radar,MIMO system could improve exploration capability.According to the MIMO radar model,a method for angle and Doppler frequency estimation in bistatic MIMO radar is presented.The algorithm does not deal with muti-dimensional nonlinear peak search,and only need eigenvalue decomposition,so its speed is fast,and the results can be paired automatically.Theory analysis and simulation results verify the validity and feasibility of these methods.
