Joint Power and Bandwidth Allocation in Collocated MIMO Radar Based on the Quality of Service Framework

The simultaneous multi-beam working mode of the collocated multiple-input and multiple-output (MIMO) radar enables to track multiple targets simultaneously. A joint power bandwidth allocation algorithm in a MIMO based on quality service (QoS) framework is proposed for multi-target tracking problem with different threat levels. Firstly, posterior Cramer–Rao lower bound (PCRLB) concerning derived. In addition, optimal objective functions are designed QoS framework, solved using convex relaxation technique cyclical minimization algorithm. numerical results show that has better accuracy achieves more reasonable resource compared strategies such as average allocation.
