背景使导弹对准目标的制导系统必须能够避免干扰信号,这种干扰信号可能是故意制造的,也可能是自然界中的假信号。光学指令制导系统是高精度的,在抗干扰能力方面降低了导弹受干扰的影响。然而,指令制导系统的导弹信标和信标跟踪器受干扰的影响仍然很高。光学驾束制导系统在USP 3 398 918中作了介绍,导弹从发射站到目标是被制导的。激光源和辐射扇形光束的光学装置均在发射站内。四个扇形光束被独立地调制,形成围道的四个光壁以导引导弹射向目标。在导弹到达目标之前,它一直在围道内跳飞。与这种光壁制导法不同,本专利提出一种比例制导系统即有两个光束在彼此互相垂直的方向内扫描导引体积,使导弹定向。
Background Guidance systems that target missiles at a target must be able to avoid interfering signals that may have been intentionally made or may be false signals in nature. Optical command guidance systems are highly accurate and reduce the impact of missiles on interference immunity. However, the impact of the guided beacon and beacon tracker of the ISS is still high. The optical beam guidance system is described in USP 3 398 918 where the missile is guided from the launch site to the target. The optical devices of the laser source and the radiation fan beam are both in the transmitting station. Four fan beams are independently modulated to form four light walls of the enclosure to guide the missile to the target. Before the missile reaches its target, it has been flying in the enclosure. In contrast to this light-wall guidance method, this patent proposes a proportional guidance system in which two light beams scan the guide volume in mutually perpendicular directions to orient the missile.
