An Efficient Multi-target Localization Method for Distributed MIMO Radar

摘要

This paper studies a multi-target localization method for distributed Multiple-input Multiple-output (MIMO) radar. We assume that the sets of time delays have already been estimated by a pre-processing algorithm. Based on the assumption, we propose a search pairing method based on ellipse model to locate the multi-target. Simulation results demonstrate that the proposed method effectively accomplishes multi-target localization with the distributed MIMO radar across scattering cross-section (RCS). Comparisons are given to present that the proposed method outperforms the existing method both at the search time and the localization accuracy.
