摘要

Collocated multiple input multiple output(MIMO)radar,which has agile multi-beam working mode,can offer en-hanced multiple targets tracking(MTT)ability.In detail,it can il-luminate different targets simultaneously with multi-beam or one wide beam among multi-beam,providing greater degree of free-dom in system resource control.An adaptive time-space re-source and waveform control optimization model for the collo-cated MIMO radar with simultaneous multi-beam is proposed in this paper.The aim of the proposed scheme is to improve the overall tracking accuracy and meanwhile minimize the resource consumption under the guarantee of effective targets detection.A resource and waveform control algorithm which integrates the genetic algorithm(GA)is proposed to solve the optimization problem.The optimal transmitting waveform parameters,sys-tem sampling period,sub-array number,binary radar tracking parameter xi(tk),transmitting energy and multi-beam direction vector combination are chosen adaptively,where the first one realizes the waveform control and the latter five realize the time-space resource allocation.Simulation results demonstrate the effectiveness of the proposed control method.
