Guidance law for a modern munition

While the PN (Proportional Navigation) guidance is known generally in the study of the missile guidance, there are not broadly known guidance laws for the munitions. Some guidance laws like the Impact Point Prediction, Modified Proportional Navigation Guidance, and Neural Network are considered currently. In this paper, we suggest the new guidance law of using the sensitivity. The sensitivity is a value about the relationship between the variation of velocity and the impact point error. Finally, we simulate the trajectory correction of the munition through this guidance law.
