针对卫星通信系统在恶劣电磁环境下单一技术体制抗干扰效果不佳的情况,发展了多域协同抗干扰技术。该技术基于凸集投影理论,把时、频、空域等多种抗干扰技术进行有机融合,从不同的角度和层面进行多域协同处理,使得干扰能够最大化地消除。该技术通过域间或域内的切换技术作为基本实现,可促进发展卫星通信系统中的多模式、多频段和多平台协作通信,实现通信信号的多参数实时变化,加强抗干扰、反侦察和抗截获的一体化设计。

Since the effect of single anti-jamming technology in the harsh electromagnetic environment for satellite communication system is poor, there is a developed technology of multi-domain collaborative anti-jamming based on convex set projection, which combines plenty of anti-jamming technology in time-domain, frequency-domain and spatial-domain. This technology is multi-layer processed and eliminates the jamming maximally. It appears the handover technology of intra-domain and inter-domain basically, and promotes to develop the multi-mode, multi-frequency and multi-plat communication of satellite communication system, realize the communication signal parameter real-time mutative, and integrate anti-jamming, counter-reconnaissance and anti-interception.
