摘　　要：针对相控阵火控雷达多任务调度时的资源分配问题,提出一种综合优先级下的自适应调度算法。基于相控阵火控雷达需与高炮配合对待拦截目标进行火力打击的特性,进行目标射击有利度求解。利用两级二维优先级表级联的思想,结合目标射击有利度、工作方式优先级和任务截止期进行综合优先级规划。以加权时间偏移量平方和最小作为调度代价准则,构建任务调度代价模型,提出带有时间窗的一步回溯法与插空法相结合的自适应调度算法,并利用该算法求解调度模型。通过仿真将本文所提调度算法与传统工作方式优先级加截止期调度算法进行对比分析,结果表明:相比传统调度算法,本文所提调度算法提升了射击价值率,降低了平均时间偏移率和调度代价。An adaptive scheduling algorithm based on comprehensive priority is proposed to address the problem of resource allocation in multi-task scheduling of phased-array fire control radar.Given that phased-array fire control radar needs to cooperate with anti-aircraft guns to attack the targets,the firing favorability is solved.Using the idea of two-level two-dimensional priority list cascade,the comprehensive priority planning is carried out with the firing favorability,working mode priority,and task deadline being taken into consideration.Taking the minimum sum of squares of weighted time offsets as the scheduling cost criterion,a task scheduling cost model is constructed,and an adaptive scheduling algorithm combining one-step backtracking method with time window and space insertion method is proposed.In addition,the algorithm is used to solve the scheduling model.The proposed scheduling algorithm is compared with the traditional scheduling algorithm employing working mode priority and deadline through simulation.The results show that the proposed scheduling algorithm has higher firing value rate and lower average time offset rate and scheduling cost.
