依据假目标干扰理论、再入段弹道式目标运动理论以及雷达散射特性，结合国内外弹道导弹突防重诱饵的研究现状，提出了基于气动阻力系数的弹道导弹非动力型重诱饵概念模型，设计一种与目标外形相似、但体积小、质量轻的弹道导弹再入段突防伴飞重诱饵。同时结合弹头阻力系数的影响，设计一种通过形态设计、代替发动机调姿的弹道导弹再入段的伴飞。对干扰核心组件的性能参数进行计算，设计了雷达无源干扰组件结构。最后，对核心干扰组件的雷达散射性进行仿真和实验测试，为弹道导弹突防的再入段伴飞式重诱饵的研究提供理论基础和数据支撑。

Based on false target jamming theory, ballistic target motion theory in re-entry phase and radar scat. tering characteristics, a concept model of non-power heavy decoy with reference to aerodynamic drag coefficient isproposed. And a kind of accompanying heavy decoy in ballistic missile penetrating re-entry phase, with the samesize, much smaller volume and lighter weight is designed, which combines with the domestic and foreign researchstatus. And in consideration of the effect of warhead resistance coefficient, accompanying in ballistic missiles re-en. try phase is realized by morphological change instead of engine adjustment. Also, a structure of passive radar jam.ming component is established by calculating performance parameters of the core component. At last, the radar scat.tering characteristics of the core jamming components are simulated and experimentally tested, which provides thetheoretical basis and data support for the research onaccompanying heavy decoy in ballistic missile penetrationre-entry phase.
