摘要
为了发挥可瞄准战斗部的定向优势,提高武器系统的毁伤效能,在弹体坐标系中建立了可瞄准战斗部瞄准方向的数学模型,在红外成像制导/激光测距一体化引信技术的基础上,采用空间几何的方法推导了弹目遭遇的交会参数。针对可瞄准战斗部侧向攻击和前向拦截目标这两种作战模式,分别分析了可瞄准战斗部如何通过这些交会参数使破片瞄准方向指向目标并适时引爆战斗部的引战配合模型,并根据成像制导/测距一体化引信所提供的信息参数对这两种模型进行了仿真分析,证明了模型的有效性,这两种模型对成像制导/测距一体化引信的设计和可瞄准战斗部的工程应用具有实际的参考价值。
In order to achieve enhanced lethality by implementing the aimable warhead, the aiming direction of the warhead was parameterized in missile coordinate system, and the missile-target terminal encounter parameters were derived with space analytic geometry method based on IR-imaging guidance and laser-ranging integrated fusing technology. According to the two encounter concepts of the aimable warhead side-attack target and forward-intercept target at endgame, the coordination models of fuse and aimable warhead were studied separately in detail, so that the aimable warhead system could aim at target and detonate the warhead after the optimum time delay to place fragments on the target during endgame. Simulation results show that IR-imaging guidance and laser-ranging integrated fusing is able to provide the required information to the aimable warhead, so the two models are valuable reference for the design of ranging-imaging guidance integrated fusing and the engineering application of the aimable warhead.
