Technical Field

[0001] The invention belongs to the technical field of airborne laser beam-riding composite space coding guidance, and in particular relates to an airborne remote control guidance device. Background Art

[0002] In modern warfare, precision-guided weapons have gradually become an important part of the information battlefield. Compared with precision strike methods such as infrared imaging guidance and television guidance, laser-guided weapons are widely used in wars due to their high precision, simple structure, low price, and easy modification, becoming the most widely used precision-guided weapons. Laser beam-riding guidance is the most widely used guidance method in laser guidance. The telescope system first captures and tracks the target, launches the missile at the best angle, and makes the missile enter the modulated laser beam. The direction of entering the beam should be as consistent as possible with the direction of the laser beam axis. During the flight of the missile, the laser receiver on the missile receives the laser signal directly irradiated by the laser, and processes the error required for guidance, that is, the direction and size of the deviation between the missile and the axis. And send this error amount to the missile's control system, which controls the flight direction and attitude of the missile, always keeps the missile and the laser beam coincident, and finally guides the warhead to the target.

[0003] Laser beam riding guidance has matured in the field of ground-to-ground precision guidance. In order to promote technological progress and expand the application field of laser beam riding guidance, so that it can be used in air-to-ground and air-to-air precision guidance, it is necessary to verify the feasibility of laser beam riding guidance air-to-ground and air-to-air guidance.
