Anti-air intercepting aircraft guidance method based on speed control

Abstract

The invention discloses an anti-air intercepting aircraft guidance method based on speed control and belongs to the guidance law research field of anti-air intercepting aircrafts. Step 1, the motion position of a target is predicted according to Kalman filtering; step 2, the encountering point position of an aircraft and the target is designed; step 3, the speed, launch time and the emission angle are calculated according to the encountering point position designed in the step 2; step 4, after the aircraft is launched, if the motion state of the target is changed, whether the position of the encountering point is updated or not needs to judged; and step 5, finally, the aircraft encounters with the target in the encountering point position. With the anti-air intercepting aircraft guidance method based on speed control, the moving direction and speed of the target are controlled, and finally the target is accurately targeted by means of the target motion predication technology and the encountering point design technology.

Description

technical field [0001] The invention relates to a guidance scheme design of an air-to-air interception aircraft, which belongs to the research field of guidance laws of an air-to-air interception aircraft. Background technique [0002] The various control technologies of modern aircraft are mainly to control the speed and direction of the aircraft in general. The control methods are mainly the application of the inclined nozzle engine, the control of the spoiler and the control of the rudder. Generally speaking, these methods mainly control the speed and direction of the aircraft. The advantages of this control method are that its control technology is relatively simple, it has the ability to produce continuously changing control force, and the control equipment of the aircraft is relatively simple. However, this method may increase The larger the curvature of the ballistic trajectory, the higher the overload capability of the aircraft, the lower the efficiency of guidance ...

Generally speaking, these methods mainly control the speed and direction of the aircraft. The advantages of this control method are that its control technology is relatively simple, it has the ability to produce continuously changing control force, and the control equipment of the aircraft is relatively simple. However, this method may increase The larger the curvature of the trajectory, the higher the overload capability of the aircraft, the lower the efficiency of guidance and control, and the low utilization rate of information, which is not conducive to the accurate hitting of the aircraft.
