摘要:

针对传统全空域相控阵波束形成方法固定占用阵列资源导致波束形成数量受限的问题,提出基于阵列资源机会式动态复用的波束形成方法。首先,分析传统全空域相控阵波束形成机理,挖掘阵面空间自由度,提出阵列资源机会式利用思路。然后,通过在阵列资源分配过程中增加阵元冲突约束,将机会波束形成过程建模为阵列资源时空二维分配问题,并通过差分进化算法求解。仿真结果显示,80低轨卫星任务配置下,所提机会式波束形成方法同时形成波束数量可增加200%,测控任务满足率提升可达53%,表明所提方法可实现全空域相控阵瞬时波束数量与任务满足率的显著提升。

Abstract:

Addressing the issue of limited beam-forming quantity due to the fixed occupation of array resources in traditional full-airspace phased array beam-forming methods, a beam-forming method based on opportunistic dynamic reuse of array resources is proposed. Firstly, the beam-forming mechanism of traditional full-airspace phased array is analyzed to explore the spatial degrees of freedom of the array, and an opportunistic utilization approach is proposed for array resources. Then, by adding element conflict constraints during the allocation process of array resources, the opportunistic beam-forming process is modeled as a two-dimensional allocation problem of array resources in both time and space, and solved using a differential evolution algorithm. Simulation results show that under the configuration of 80 low-Earth orbit satellites, the proposed opportunistic beam-forming method can increase the number of simultaneously formed beams by 200%, and enhance the satisfaction rate of telemetry, tracking and control (TT&C) tasks by up to 53%, indicating that the proposed method can achieve significant improvements in both the number of instantaneous beams and the task satisfaction rate of full-airspace phased arrays.

Key words: full-airspace phased array, beam-forming, array resource
