雷达是现代战争中重要的全天候探测设备,也是敌方电子干扰的重点目标。 美空军《作战条例》明确规定:为提高战机的生存能力,任何作战飞机在执行空中作战任务时,都必须配有随队电子战飞机护航。 未来战争的空中作战必定是双方在强干扰背景下的体系对抗,随着干扰技术的不断发展,雷达系统需要具备更强的抗干扰能力。 对于越来越复杂的电磁环境,特别是主瓣干扰,传统的空域抗干扰技术已经无法满足抗干扰需求,多平台联合为雷达提供了更多的资源和更大的系统自由度。 文中在分析干扰样式及抗干扰的主要措施的基础上,分析研究了基于多平台的的抗干扰技术。

Radar acts as a significant all-weather detection equipment in modern warfare, meanwhile, it has become a main target jammed by adverse ECM equipment. It is specified in US air force ‘operating regulations’ that any aircraft executing air combat task must be accompanied by escort ECM aircraft to improve survivability of the aircraft. The future warfare will feature SoS countering in severe jamming background. With the continuous development of ECM technologies, radar system must possess superior ECCM capability. Conventional spatial ECCM technologies can’t meet jamming rejection requirement in severer and severer EM environment especially for main lobe jamming. Multi-platform combination provides more resource and system freedom for radar system. In this paper, multi-platform based ECCM technology is studied based on analyzing jamming type and major ECCM measures.
