Aircraft Laser Guidance Control System and Method Equipped with Pilot Helicopter

Abstract

The invention discloses an aircraft laser guidance control system and method equipped with a pilot helicopter. The system and method provide a pilot laser for the aircraft through a pilot helicopter that can hover, and utilize the rapid maneuverability of the unmanned aerial vehicle to ensure the guidance laser It can continuously irradiate the target, and at the same time that the helicopter provides the guidance laser for the aircraft, it also calculates the target coordinates by itself according to the received diffuse reflection laser signal, and transmits the target coordinates to the aircraft through signal transmission, so that the aircraft immediately The target coordinates detected by its own seeker can be used for guidance and control, and the received target coordinates can also be used as a supplement, so as to accurately calculate the guidance command when its own seeker fails to obtain the target coordinates.

Description

Technical field [0001] The present invention relates to the field of aircraft guidance control, and more particularly to a aircraft laser guidance control system and method for configuring a pilot helicopter. Background technique [0002] The laser guidance controls the aircraft flies to the target position is currently a commonly used guidance control method, which transmits the laser beam of a particular frequency band to the target position, and receives a laser signal that is reflected by the target by the guiding head mounted on the aircraft, and Track the laser signal, so that the aircraft knows the target position, providing the target position information for the guidance control; [0003] During the actual work, the external environment of the aircraft and its own flight status are complex and more variable. When the flight speed of the aircraft is close to the sound, some aircraft can be flying even if they did not reach the sound. Jitter phenomenon, in addition, is aff...

AI Technical Summary

Problems solved by technology

[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

[0004] In addition, if the target is mobile, there may be a problem of occlusion between the laser emission point and the target, especially in the case of complex terrain, in order to ensure that the laser signal can continue to irradiate the target, it is necessary to make the laser irradiation point have the ability to prevent occlusion
