Abstract

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
