摘要
通过对被动微波/红外成像舰空导弹复合导引头交班问题的研究,建立了复合导引头制导控制系统的数学模型,复合导引头跟踪回路主要由被动微波相位干涉仪与红外成像导引跟踪回路组成。以此模型为基础,进行了防御反舰导弹类目标典型运动情况下的交班过程仿真。分析了各因素在交班时对弹道扰动程度的影响。得出目标机动能力越强、速度越快、弹目距离越近,交班引起的弹道扰动越大;舰空导弹在拦截反舰导弹时,在反舰导弹巡航段进行拦截并交班时,交班过程引起的弹道扰动最小的结论。
The handover problem was analyzed by studying passive microwave and infrared imaging composite guidance ship-defense missile, and the mathematical model of guidance and control system of composite seeker was built.The tracking loop of this composite seeker was composed of passive microwave phase interferometer and infrared imaging seeker tracking and guidance loop. Based on the mathematical model, the handover process in typical movement were simulated, in which the target such as anti-ship missile was defensed by anti-aircraft missile, the influence of various factors on the trajectory disturbance during handover was analyzed. Finally,the conclusion are drawn that the more powerful the maneuverability of target, the faster the velocity of target, the nearer the distance between missle and target, the larger the trajectory disturbance during handover.During the ship -defense missile defenses the anti-ship missile, when it intercepts anti-ship missile of cruise stage,and hands over, the minimum trajectory disturbance is obtained.
