Fiber-optic guided missiles are a new type of tactical weapon that has developed rapidly in recent years. It integrates fiber-optic television cameras, optical sensors, computer data processing and control technology. It is a powerful weapon against tanks, ships and helicopters on the battlefield.Fiber-optic guidance is an image guidance technology that uses optical fiber for two-way data transmission. After the missile is launched, the optical fiber is continuously released from the optical fiber tube of the missile. When it flies to the cruising altitude, the image seeker on the head of the missile detects the target video information and transmits it to the guidance station through the optical fiber. The shooter can clearly observe the ground, sea or air targets. The guidance device generates control instructions and transmits them to the missile through the same optical fiber to control its flight.Fiber-optic guidance can adopt the post-launch locking method. The missile is launched vertically in a hidden place. The shooter does not have to maintain direct visual contact with the target, so it is suitable for combat in various environments.The main advantages of fiber-optic guidance are1. The hit rate is extremely high because it is an image guidance. The shooter can clearly see the target through the monitor, and the non-line-of-sight range is used for accurate guidance.2. Long range, beyond the range of enemy firepower, can attack ground and armored targets from the top, thus improving the survivability of weapon systems and shooters.3. High reliability. Since the guidance information is transmitted in the optical fiber, it is not easy to be detected and interfered. The flight speed is high and its volume is small, so it is not easy to be intercepted. Small volume and light weight. The original two cables in the wired guidance are replaced by one optical fiber, which is more than ten kilometers long and weighs only a few hundred grams, thus reducing the mass and volume. It has a high cost-effectiveness. Expensive information processing equipment is fully equipped on the launch pad and can be used repeatedly, thereby simplifying the structure of the missile and reducing the cost.
