Even if flying outside the atmosphere, in order to ensure hit-kill the target, the common radar seeker had better not be used either. It is possible for the TBM defense interceptor to hit to kill the target or to kill the target to draw support from a strengthen kill-device with a radar seeker of high range resolution ratio or a high precision LWIR stare-image seeker, by gas thrust vector control system or gas thrust vector control/aerodynamic control system, to make use of optimum guidance law. The statically stable interceptor with gas dynamic control system in the atmosphere has the advantages that the fuel consumption of the attitude control engine is small and the error of body's angular velocity is little in the period of stabilization control. To achieve long distance ascent-phase intercept, such as the ground-launched TBM defense interceptor located in the point TBM attacking, very high demands are raised to the TBM defense system and the TBM defense interceptor, because the increase in interceptor mass is about one percent if the stand off range of the interceptor increases one kilometer, and the increase is about six percent if the intercept altitude decreases one kilometer or the reaction time of the TBM defense system increases one second for flight time of 60 to 90s, altitude of 50 to 80km and stand off range of 300 to 600km.
理论研究与数字仿真结果表明：大气层内采用普通雷达导引头的反TBM拦截器无论采用空气动力控制还是直接侧向力控制，都难以实现与目标的直接碰撞，即使在大气层外飞行，要确保与目标直接碰撞，也不宜采用普通雷达导引头，而采用高距离分辨率雷达导引头或高精度LWIR凝视成像导引头，利用直接侧向力控制或直接侧向力／空气动力复合控制方式，运用最佳制导规律的反TBM拦截器实现与目标的直接碰撞或利用杀伤增强装置杀伤目标是可能的；大气层内燃气动力控制的静稳定拦截器稳定控制时具有姿控发动机能耗少、弹体角速率误差小的优点；远距离拦截处于上升段TBM时，如采用在TBM攻击区域的地基拦截方案，对TBM防御系统及反TBM拦截器均提出了很高的要求，因为射程每增加一公里，拦截器的质量将增加百分之一左右，拦截高度每降低一公里或TBM防御系统反应时间每增加一秒，反TBM拦截器的质量将增加百分之六左右（针对射程300～600km，拦截高度50～80km，飞行时间60～90s的情况）。
