Multi-target localization using geometric model for distributed MIMO radar

The multi-target localization method for distributed multiple-input multiple-output (MIMO) radar is investigated in this paper. A geometric-model-based method is proposed for multi-target localization and it is still efficient in the case when some targets with multiple spatial reflections become unobservable in some transmitter-receiver channels. Weight coefficients are used to determine the position of targets. Simulation results demonstrate that the proposed method effectively accomplishes multi-target localization with the distributed MIMO radar across scattering cross-section (RCS) and it outperforms the existing method both at search time and localization accuracy.
