摘　　要：现代战场电磁环境日益复杂,干扰特别是主瓣干扰对雷达探测产生了极大威胁。本文从雷达作用域角度系统地梳理了现有反主瓣干扰方法,主要包括空域、极化域、时域以及多域间的联合。着重介绍了代表性成果及其最新进展,分析了其中存在的问题,指出了研究中现存的难点。在这基础上,展望了未来雷达反主瓣干扰的三个发展方向,包括战场电磁环境感知技术、从体制上形成对干扰机的优势以及反干扰信号处理中采用的新途径和新算法。The electromagnetic environment of modern battlefield is complex increasingly. Interference, especially mainlobe interference threatens radar detection seriously. The available mainlobe interference suppression means are listed from perspective of radar action scope systematically including airspace, polarization domain, time domain and combination of multiple domains. The representative achievements and its latest developments are presented, existing issues are analyzed, and existing difficulties in study is given. Based on the analysis, three development directions of radar mainlobe interference suppression in future are prospected, including battlefield electromagnetic environment awareness technology, the advantages for jammer formed in system, and adoption of new approaches and algorithms in anti-jamming signal processing.
