摘　　要：针对相控阵火控雷达负载饱和情况下的时间资源分配主观性强、雷达任务调度及时性差的问题,结合任务综合优先级,提出一种基于改进时间指针的相控阵火控雷达任务调度算法。该算法在传统时间指针算法的基础上增加调度前比较环节,即提取当前时刻综合优先级最高的两个任务,选择时间偏移量较小的任务进行调度。仿真结果表明:相比于传统时间指针调度算法,改进后的算法提升了任务的调度成功率、时间利用率和射击价值率,降低了平均时间偏移率。Aiming at the problems of highly subjective time resource allocation and poor timeliness of radar task scheduling of phased array fire control radar under the condition of load saturation,a task scheduling algorithm based on modified time pointer and comprehensive task priority is proposed.The proposed algorithm adds a pre-scheduling comparison link to the traditional time pointer algorithm.In this link,the two tasks with the highest comprehensive priority at the current moment are extracted,and the task with a smaller time offset is selected for scheduling.The simulation results show that the proposed algorithm improves the task scheduling success rate,time utilization rate,and firing value rate.In addition,it reduces the average time offset rate.
