Effect of instruction delay on handing over midcourse to terminal guidance of ship-to-air missile

In the cooperative guidance of long and medium-range ship-to-air missile for visual range targets,the precision of handing over midcourse to terminal guidance of ship-to-air missile is affected by the delay of targets position instruction.To solve this problem,the models of seeker pointing error and velocity vector pointing error for handing over midcourse to terminal guidance were designed based on the fact that targets fly straight and maneuver.Moreover,the corresponding error modification method was proposed,and the simulations were carried out to validate the models′ validity.
