The existing positioning methods for the automatic guided vehicle (AGV) in port can not achieve high location precision, Therefore, a novel multiple input output (MIMO) antenna radar scheme is proposed this paper. problem AGV considered, and joint estimation direction of departure (DoD) arrival (DoA) addressed multiple-input multiple-output system. With detect transponder estimate DoA/DoD, relative between be obtained. corresponding Cramér–Rao lower bounds (CRLBs) target parameters are also derived theoretically. Finally, we compare accuracy traditional global position system (GPS) with MIMO Simulation results show that method better performance than GPS.
