Anti-air intercepting aircraft guidance method based on speed control

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
