摘要
以导弹末制导雷达为威胁源,以质心干扰为前提,通过理论分析了导弹、飞机和箔条弹相对运动情况,并建立了箔条弹发射后反射截面积的变化模型。在此基础上,结合导弹跟踪飞机的具体跟踪方法和跟踪过程,建立相应的攻击和干扰模型,推导得出箔条弹的弹间隔、弹数、组间隔、组数以及箔条弹的投放时机,提高了箔条干扰的效率。最后,以特定环境为例,验证了相应的理论分析。
Taking the missile terminal guidance radar as the threat on the premise of centroid jamming, the paper analyzes the relative motion of missile, plane and chaff cartridge. And the model of the chaff cloud's RCS is built. Based on this and combined with the practical tracking method and process, the corre- sponding attack and interference model is built. The numbers and intervals of chaff decoys and chaff decoy groups, as well as the diffusing time are derived. The efficiency of the chaff jamming is improved. In the end, taking a specific environment as example, the corresponding theoretical analysis is verified.
