摘要/Abstract

摘要：

目标高速运动使得MIMO雷达回波信号经通道分离后各通道的距离和多普勒频率均不在同一分辨单元，此时，无法利用传统的超分辨算法对目标距离、角度等参数进行估计．本文利用速度估计值构造补偿因子，对回波信号进行预处理，校正距离和多普勒单元走动，再利用空间谱估计算法对目标多维参数进行估计．仿真结果表明了所提方法与MUSIC相比，具有更好的可行性和有效性．

Abstract:

In Multiple-Input Multiple-Output (MIMO) radar, the separated echoes of a target with a high speed are located in neither the same range bin nor the same Doppler bin. As a result, the parameters (including range, azimuth and elevation) of the target can't be estimated using the traditional supper-resolution algorithms. In this paper, velocity estimation is used to form compensation expression, which pre-processes the echoes. And the range and Doppler migration are corrected. Then the spatial spectrum estimation algorithm is applied to the corrected echoes to obtain the range, azimuth and elevation of targets. Simulation results indicate that the feasibility and validity of the methods presented are better than those of MUSIC.

Key words: MIMO radar, spatial spectrum estimation, multi-dimension parameters estimation
