摘　　要：认知雷达通过模仿人类认知功能实现智能化,在与环境交互作用下自适应调整雷达收发功能以实现性能提升。针对传统粗放式时间能量资源管理策略性能较差的问题,基于认知先验信息,在基于MIMO的认知雷达近距离范围内采用脉冲宽度分割方法形成多个正交波束跟踪多个目标,实现能量的充分利用,节约雷达时间资源,提升雷达性能。仿真结果显示,对于雷达场景中的目标数量较大情况下,相对于传统的雷达时间能量资源管理方法,本文提出的方法在保证跟踪精度符合要求的前提下,能够有效降低认知雷达时间资源开支。Cognitive radar can operate intelligently by imitating human cognition process.It adaptively adjusts its receiver and transmitter configuration based on its interaction with the environment to improve its performance.However,traditional extensive time and energy resource management strategies lead to poor performance.In this paper,pulse width is divided into several parts to form multiple orthogonal beams and track multiple targets based on prior cognitive information in close range applications of cognitive MIMO radars.With this method,radar power is fully utilized,radar time resource is saved,and radar performance is improved.The simulation results show that the proposed method can effectively reduce the radar time resource consumption with the required tracking accuracy being ensured in radar applications where there are a large number of targets.
