**Author(s): ***Florentin Moraru* *Liviu-Cristian CocoÅŸilÄƒ*

**Abstract: **In this paper, we shall consider the case of a self-guided rocket that follows its target using the proportional navigation law. This paper presents the mathematical model to calculate the performances of an infinite stability rocket (missile) in the case of ideal guidance. We utilize both the equations of motion in polar coordinates and the equations of motion in intrinsic coordinates to model the rocket which tracks the target in the case of the plane motion. The paper contains three particular case studies for this type of rocket (high maneuvering rocket).
