摘要

Compared with the traditional phased array radar,the co-located multiple-input multiple-output (MIMO) radar is able to transmit orthogonal waveforms to form different illuminating modes,providing a larger freedom degree in radar resource management.In order to implement the effective resource management for the co-located MIMO radar in multi-target tracking,this paper proposes a resource management optimization model,where the system resource consumption and the tracking accuracy requirements are considered comprehensively.An adaptive resource management algorithm for the co-located MIMO radar is obtained based on the proposed model,where the sub-array number,sampling period,transmitting energy,beam direction and working mode are adaptively controlled to realize the time-space resource joint allocation.Simulation results demonstrate the superiority of the proposed algorithm.Furthermore,the co-located MIMO radar using the proposed algorithm can satisfy the predetermined tracking accuracy requirements with less comprehensive cost compared with the phased array radar.
