摘要/Abstract

摘要： 多输入多输入（MIMO）雷达是最近几年提出来的一种新体制雷达，在探测目标空间位置时，若空间目标相关，很多算法将会失效。针对该问题，提出一种双基地MIMO雷达的相关目标定位方法，通过在MIMO雷达的发射端和接收端构造虚拟阵列，从而实现空间相关目标信号的解相关，得到空间目标正确的位置，且估计参数自动配对。该方法避免了阵列孔径损失，估计精度高。理论分析和计算机仿真结果验证了该算法的有效性。

Abstract: The Multiple-Input Multiple-Output (MIMO) radar was proposed in recent years. Using MIMO radar to detect the location of multi-target, a lot of algorithms are failure when the multi-target echo signals are coherent. Concerning this problem, a localization algorithm of coherent multi-target is presented in bistatic MIMO radar. The algorithm constructs virtual array for both the transmit and receiver array to de-correlate the coherent multi-target echo signals, and then the location of multi-target can be obtained. The estimated parameters are automatically paired without additional paring computation. The proposed method avoids the array aperture loss and the performance of angle estimation is improved. Theoretical analysis and simulation results verify the effectiveness of this method.
