Influence of Target Missing on Terminal Ballistic Trajectory of Terminal Guidance Projectile

Target missing and target re-capturing may happen in the terminal ballistic trajectory of terminal guidance projectile because of the factors as jamming and/or weather.To gain the relation between the terminal ballistic trajectory character and the time of target missing,the terminal guidance projectile control model was set up according to small disturbance theory.The trajectory character when missing target and re-capturing under different target maneuvering conditions was simulated.The simulation result for the target at uniform motion and uniform varying motion was analyzed,which demonstrated that the target missing during terminal trajectory has remarkable impact to projectile's terminal ballistic trajectory character,especially when the target is in maneuvering.
