摘　　要：机载箔条干扰系统作为目前作战飞机对付雷达末制导导弹的一种重要机载自卫装备,在航空自卫电子对抗系统中占据着非常重要的地位。为了更为确切地揭示机载箔条干扰系统的具体干扰能力,分析了机载箔条系统干扰原理,给出了箔条弹运动模型、箔条云雷达散射截面模型、导弹运动模型,在质心干扰工作原理基础上,建立了机载箔条干扰系统干扰能力的评估模型。最后通过计算机仿真计算,得出不同情况下机载箔条干扰系统的干扰能力。The airborne chaff interference system becomes an important airborne self-defense equip- ment to protect combat airplane from radar terminal-guided missiles attack, and it plays an important role in airborne self-defense ECM. In order to reveal the concrete interference capability of the air- borne chaff interference system, the jamming principles of the airbome chaff interference system is an- alyzed. The models of chaff cartridge movement, the radar cross section of chaff cloud and the propor- tional-guided missiles movement are put forward. Foundation on the chaff eentroid jamming princi- ples, the evaluation model for the interference capability of the airborne chaff interference system is built. Finally, according to calculation of computer simulation, the interference capability of the in- terference system is achieved in the term of different conditions.
