摘要: 针对天基光学传感器网络实时调度算法的局限,深入分析目标运动特征,提出一种传感器预指派模型.在多目标传感器资源需求紧耦合和松耦合条件下,引入实时修正机制,分别提出基于修正粒子群优化和分段指派的传感器动态预指派算法.资源需求紧耦合和松耦合场景下仿真实验表明,动态预指派算法虽然需要较长时间的预先指派过程,但其实时修正的运算效率明显高于实时调度算法,为上层系统设计留下更多富余时间.

Abstract: To deal with the limitation of real-time scheduling algorithm of space based optical sensor network,the object characteristics was deeply analyzed,and a sensor pre-assignment model was proposed.Furthermore,the real-time modification was introduced,and the dynamic sensor pre-assignment algorithms based on modified particle swarm optimization and segmented pre-assignment were proposed,under the condition of different demand couple,i.e.tight couple and loose couple.Simulations conducted under the condition of tight couple and loose couple show that,the dynamic sensor pre-assignment algorithm needs long-time pre-assignment process,but the computation efficiency of real-time modification exceeds that of real-time scheduling algorithm,which can leave more margin time for the upper system.

Key words: low earth orbit constellation, sensor networks, scheduling algorithms, pre-assignment, tracking
