Phased array radar with a flexible and fast to find and track the ability of the target and multi-functional,adaptive ability and so on.Due to the beam agility capability of the array antenna,the multi-function phased array radar can alternately search,verify and track the operation of multiple targets.Therefore,how to allocate the task of resource allocation to the overall performance of the optimized radar plays a very important role under the premise of limited time resources,energy resources and computer resources.Before the radar resource is scheduled,the tasks need to be prioritized.According to the priority of each task priority scheduling.In the existing priority sorting algorithm,only the priority of each task for a sort,this will make a lot of relatively low priority but more urgent task is discarded,resulting in a reduction in the number of successful scheduling tasks.Aiming at this problem,a quadratic scheduling algorithm is proposed to innovatively use the secondary scheduling in the scheduling module.The algorithm combines the priority and deadline of the idea of the task of the second scheduling,can be a scheduling interval to perform more resident tasks.As a result,the loss rate of the task is reduced and the resource utilization of the radar is improved.The task priority is sorted for the next scheduling module.Due to the limited resources of the system,the resource scheduling algorithm plays an important role in how to allocate tasks as much as possible under the limited radar system resources.One of the more common methods is the adaptive pulse interleaving scheduling algorithm.Although the algorithm has been improved in the utilization of radar resources,but usually only consider some simple radar resource constraints,so the use of radar resources is not sufficient.Aiming at this problem,an optimized pulse interleaving algorithm is proposed.The algorithm references the time pointer to traverse the waiting time of the waiting period,and receives or transmits other pulses without affecting the previous pulse reception and transmission.The simulation results show that the algorithm can optimize the scheduling performance from each evaluation index,and verify the effectiveness of the algorithm.The simulation results show that the proposed algorithm can be used to evaluate the performance of the algorithm.Especially in the scheduling of the time when the performance of this algorithm reflects the more obvious,to achieve the purpose of efficient scheduling.Finally,a radar task scheduling simulation system is designed,and the simulation system is implemented in MATLAB GUI environment.The simulation system is now based on the quadratic scheduling and temporal pointer pulse interleaving algorithm graphical interface.In this interface,you can set the search parameters according to different needs,tracking parameters and target parameters.Through the interface simulation button to achieve a key simulation and gives the simulation results.
