直升机机载面源红外干扰弹技术分析

机载面源红外干扰弹是对抗红外成像制导武器的一种常用装备,以产生假目标,干扰、诱骗导弹攻击,提高飞机的战场生存力。通过分析红外成像制导武器和面源红外干扰弹的技术原理,构建了地对空测试系统,获取了面源红外干扰弹的相关数据,从红外辐射强度、面积特性和时间特性三个方面进行了分析,为对抗红外制导武器提供了理论依据。最后,结合面源干扰弹的红外辐射强度、空间分布特点、投放角度、投放时机以及飞机的红外辐射特性,从红外制导导弹攻击的三个阶段,给出了干扰弹的投放策略和飞机机动策略,有助于发挥面源红外干扰弹的作战效能和干扰效果。

Analysis on helicopter airborne surface-type infrared decoy technology

Airborne surface-type infrared decoy is one of the most common equipment in countering infrared imaging guided weapons,which generates false target to interfere and inveigle missile attack in enhancing fighter combat survivability.Firstly,the mechanisms of infrared imaging guided weapon and airborne surface-type infrared decoy were analyzed.The ground-to-air test system was built,and the relevant data of surface-type infrared decoy by the system was got.Secondly,according to the data,the infrared radiant intensity,radiation area and time-domain characteristic of decoy were analyzed,which contributes to counter infrared imaging guided weapons.Finally,the strategies of launching surface-type infrared decoy and airplane maneuvers were given from three sections of infrared imaging guided weapon attack,which integrates airplane infrared radiation and characteristic of surface-type infrared decoy such as infrared radiant intensity,spatial distribution,launching angle and launching time.The strategies can contribute to perform decoy′s combat effectiveness and jamming effect completely.
