Analysis of Parabolic Trajectory Guidance Law for Airborne Missile

Abstract

Air supremacy plays a decisive role on the outcome of the war. All the countries in the world are developing the research of airborne missile. In view of this demand, we first analyze the pure tracking method, the parallel approach, the three point method and the proportional navigation method and point out the defects of the conventional trajectory method, then introduce a compound guidance law of parabolic trajectory including initial guidance, middle guidance and terminal guidance and establish parabolic trajectory system. Through the analysis of the kill probability of the conventional trajectory and the parabolic trajectory at different distances, a result is obtained: the parabolic trajectory can effectively increase the attack range of the middle-short-range missile, and can be used in the missile’s technical upgrade.
