Research on effect on target searching of image guided missile´s terminal maneuver

Probability of penetration of image guided missile can increase greatly if the missile does terminal maneuver, but the terminal maneuver may have effects on target searching of missile. To study the effect the centroid model of missile doing typical terminal weaving maneuver was built and the model of target movement and parallel search law were built too. Based on the models the effect of terminal weaving maneuver on search area, movement speed of image on monitor screen and the probability of target entering the IFOV of seeker were analyzed through simulation. Simulation results show the effect on target searching of terminal weaving maneuver is little when image guided missile attacks the target with low velocity, which provides important reference for overall design of missile.
