On endgame nonlinear correction technology of air-to-air missile

To solve the problem that the aiming point of IR air-to-air missile can not be kept the same as the ideal hit-point,a guidance method for amending endgame trajectory is proposed to correct hit-track of the missile-target,and also to improve guidance effectiveness and lethality.We educed the biased proportional guidance law and present a scheme for simplifying the guidance law.We also analyzed the endgame guidance control system with lead bias imported,and presented the method for realizing the control system.Simulation showed that the guidance precision was improved greatly,which could satisfy the requirement.
