Miss Distance Simulation for Air Defense Missile by Combined Control of Lateral Thrust and Aerodynamic Force

An ignition law of lateral pulse rockets and guidance policy of terminal correction was given for air defense missile by combined control of lateral thrust and aerodynamic force.By final miss distance simulation,the interceptibility according to the targets with different motion characteristics was studied and the influence of main error factors was analyzed.The results show that this combined control method has perfect ballistic correction ability,but it is greatly affected by the measurement error of radar seeker.
