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。
Through the research on the shift of passive seeker / SAM guided seeker, the mathematic model of the guidance and control system of composite seeker is established. The tracking of the seeker consists of passive microwave phase interferometer and infrared imaging Tracking circuit. Based on this model, the shift process simulation under anti-ship missile’s typical target movement was carried out. The influence of various factors on ballistic disturbance degree is analyzed. The result shows that the stronger the target maneuvering ability is, the faster the speed is, the closer the missile projectile distance is, the larger the ballistic disturbance caused by the shift is. The ship-to-air missile intercepts the anti-ship missile cruise section and intercepts when intercepting the anti- Caused by the smallest ballistic disturbance conclusion.
