摘要

基于旋转相控阵雷达体制特点，针对扇区饱和攻击时任务调度失败率高的问题，提出一种基于广义时间窗的预规划任务调度方法.根据雷达波束电扫范围和天线转速计算出任务的广义时间窗，当某扇区任务饱和时，在广义时间窗的约束下将任务调配到相邻的扇区.仿真实验表明，相比于传统的基于时间窗和优先级的自适应调度算法，本算法能够充分释放旋转相控阵雷达相扫潜能，有效稀释饱和攻击扇区的冲突任务，显著提高任务调度成功率和时间利用率.

Abstract

Based on the characteristics of the rotating phased array radar system

and focus on the problem of high task scheduling failure rate during sector saturation attacks

a pre-planned task scheduling method based on generalized time windows is proposed. The generalized time window of the task is calculated according to the radar beam electric scanning range and the antenna rotation speed. When the task of a certain sector is saturated

the task is allocated to the adjacent sector under the constraint of the generalized time window. Simulation experiments show that compared with the traditional adaptive scheduling algorithm based on time window and priority

this algorithm can fully release the potential of rotating phased array radar phase scanning

effectively dilute the conflicting tasks of saturated attack sectors

and significantly improve the success of task scheduling rate and time utilization.
