End Of The Air-to-air Missile Non-linear Correction

This paper does certain research on the Endgame nonlinear correction technology of the air-to-air missile. The correction technology is taken on to improve the antipersonnel probability and make the navigation more precise.Embaying the subject matter on attacking the key part of the target,The main results and contributions of this paper are as follows:First, it studies the structure of the air-to-air missile's guidance control system,introduce the process of guidance control system and analys the characteristics and mechanism of the guidance control system;The second, the proportional navigation have been analytical studied, the modified proportional navigation is given,that based on apprimimate conditions have been predigested. we deduce the biased proportional navigation and present the simplified navigation scheme. The time to set-up and the measure of lead bias are analyzed in this paper.Finally we also probe into the means on performance of control system;and then,set up the endgem guidance system model to simulation, validate the validity of the modified proportional navigation in different situation, and, analys the effects of guidance parameter on endgame correction, The results shows the effectivness of the modified proportional navigation.
