统计MIMO雷达的多目标定位和速度估计方法

A Method for Multi-Target Localization and Velocity Estimation in Statistical MIMO Radar

在多目标情况下,统计多输入多输出(MIMO)雷达需要对不同观测通道中估计出的目标参数进行配对,才能完成多个目标定位及其速度估计。针对这一问题,对统计MIMO雷达提出了一种映射搜索配对法来实现在不同观测通道中的目标距离延时和多普勒频率估计值的配对,从而获得目标位置及其速度估计值。仿真结果表明,该方法在目标雷达散射截面(RCS)闪烁情况下能对多个目标进行有效定位和速度估计。

When the statistical multiple-input multiple-output（MIMO） radar is exploited for multi-target localization and velocity estimation,the estimated parameters in the multiple observation channels have to be paired for every target.A mapping search pairing method is proposed in this paper,by which the estimated target distance delays and the estimated Doppler frequencies are paired.Then the positions and velocities of targets are solved from the successfully paired parameters.The simulation results demonstrate that the proposed method effectively accomplishes localization and velocity estimation of the multiple targets with the radar cross section（RCS）scintillations.
