[0002] In war, accurate strikes against enemy targets are a key requirement. Traditional guidance methods, such as inertial guidance, have certain accuracy limitations. With the development of science and technology, laser guidance technology has emerged. It combines the advantages of lasers and advanced guidance signal processing technology, and has the advantages of high accuracy and strong anti-interference ability.

[0003] Laser guidance is a guidance technology that uses laser beams to guide aircraft (such as missiles, bombs and other weapons) or other moving objects to accurately fly to the target. It achieves precise navigation and control by irradiating the target with lasers and receiving reflected laser signals. Although the audience knows the application of laser guidance technology, they often do not fully understand its specific working principle and working status.
