摘　　要：为提高掩护战斗机与导弹突防的干扰有效性,主瓣干扰将逐步成为未来战争中电子战装备的优先选择,远距离支援式主瓣干扰、随队式主瓣干扰和机载弹载自卫式干扰是未来海战环境中大中型水面舰艇预警探测雷达常态化面临的主要干扰场景。当干扰来自天线主瓣或近主瓣区域时,现有抗副瓣干扰技术基本失效,现役技术状态不具备有效的对抗措施,严重制约了舰载主战雷达的实战性能。从雷达抗干扰能动性角度系统地梳理了现有抗主瓣干扰方法,主要包括主动对抗和被动抑制两方面,着重介绍了单装抗干扰代表性成果及其最新进展,分析了相应算法实现思路及存在的问题。For raising the jamming effectiveness for shielding the defense penetration of fighter and missile,the mainlobe jamming will become the prior selection of electronic warfare(EW)equipment in the future war step by step.Remote support mainlobe jamming,escort mainlobe jamming and airborne/missile-borne self-defense jamming are main jamming scenes which early warning and detection radar of large and medium-sized surface ships faces normally in the future sea war environment.When the jamming comes from antenna mainlobe or near mainlobe scope,current antisidelobe-jamming technology will almost lose efficiency,and active duty technology status has no effective countermeasure,which seriously limits the actual combat performance of main shipborne radar.This paper describes current anti-mainlobe-jamming methods from the aspect of radar antijamming activity,which mainly contains active antagonism and passive suppression,emphatically introduces typical achievement of single anti-jamming and the up-to-date development,analyzes correponding algorithm realization idea and existing problem.
