Aircraft laser guidance control system and method using ground laser designator

Abstract

The invention discloses an aircraft laser guidance control system and method using a ground laser pointer. The system and method provide guidance laser light for the aircraft, and also automatically calculate the target coordinates according to the received diffuse reflection laser signal, and The target coordinates are transmitted to the aircraft through signal transmission, so that the aircraft can use the target coordinates detected by its own seeker to conduct guidance and control, and can also use the received target coordinates as a supplement, so that when its own seeker does not Accurately resolve guidance commands when target coordinates are available.

Description

technical field [0001] The invention relates to the field of aircraft guidance and control, in particular to an aircraft laser guidance and control system and method using a ground laser pointer. Background technique [0002] Controlling the aircraft to fly to the target position by laser guidance is a commonly used guidance control method at present. Track the laser signal, so that the aircraft can know the target position, and provide target position information for guidance and control; [0003] In the actual work process, the external environment of the aircraft and its own flight state are complex and changeable. When the flight speed of the aircraft is close to the speed of sound, the aircraft may vibrate violently. Vibration will also occur. In addition, due to the influence of severe weather such as strong winds and rainstorms, the air flow will become unstable, which will also affect the stability of the aircraft. When the aircraft vibrates, the seeker on it may be...

[0003] In the actual work process, the external environment of the aircraft and its own flight state are complex and changeable. When the flight speed of the aircraft is close to the speed of sound, the aircraft may vibrate violently. Vibration will also occur. In addition, due to the influence of severe weather such as strong winds and rainstorms, the air flow will become unstable, which will also affect the stability of the aircraft. When the aircraft vibrates, the seeker on it may be at a certain If the tracked laser signal is lost within a period of time, that is, the laser signal is separated from the field of view. At this time, the aircraft loses the specific target position and can only continue to fly according to the current flight attitude until the laser signal is captured again or lands. The final hit accuracy brings certain adverse effects
