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估计方法,该方法利用2次ESPRIT方法分别估计目标的多普勒频率和来波角度(DOA),然后利用ROOT-MU-SIC方法估计得到目标去波方向(DOD)。所提算法只进行3次特征值分解,避免了多维非线性的谱峰搜索,配对过程简单。仿真结果证明了该算法的有效性。
A signal model of the bistatic MIMO radar for target parameters estimation is set up, and an angle and Doppler frequency estimation algo- rithm is proposed. The ESPRIT method is used twice to estimate the Doppler frequency and the direction of arrival （DOA）, and then ROOT-MUSIC method is used to estimate the direction of departure （DOD）. The proposed algorithm only uses eigenvalue decomposition three times, and avoids the muhi-dimensional nonlinear peak search, and has simple pairing process. The simulation results show the proposed algorithm is effective.
