摘要
文中分析了预警机雷达面临的复杂地理环境和复杂电磁环境带来的杂波和干扰抑制的难题,通过回顾认知雷达的发展历程,总结了认知雷达技术"感知环境、反馈闭环,利用知识、智能决策"的内涵。并通过知识辅助空时自适应处理的认知反杂波技术以及基于环境感知的认知反干扰技术两个例子说明了认知雷达技术在预警机雷达中的应用潜力。最后对认知雷达的现状以及未来进行了总结和展望。
This paper analyzes the problem of clutter and interference suppression brought by complex geographical environment and complex electromagnetic environment which is faced by airborne early warning system( AEW).By reviewing the development of cognitive radar,it summarizes the connotation of cognitive radar technology "perceiving environment,feedback closed loop,using knowledge,intelligent decision".The application potential of cognitive radar technology in AEW radar is illustrated by two examples of cognitive anti clutter technology based on knowledge-aided space-time adaptive processing and cognitive anti-jamming technology based on environment perception.Finally,the status and future of cognitive radar are summarized and prospected.
