Testing Guidance Laws Performance

WithRafael T. Yanushevsky

Any simulation focuses on achieving certain goals to check the validity of some ideas, to make a preliminary estimate of design efficiency, etc. Each simulation model deals with a certain scenario. For missiles, the presence of a target, its parameters and trajectory, is a necessary part of the model, and the intercept accuracy is one of the most important parameters determined by simulation. For unmanned aerial vehicles, the model should test how precise the vehicle follows the prescribed flight path presented by a sequence of waypoints. Various types of missiles have their specific features which should be reflected in simulation models. Usually the six degree simulation models are used to imitate the engagement scenarios and to test the effectiveness of guidance laws. The Kappa algorithm dominates midcourse guidance in the endo-atmosphere and can be interpreted as maximization of the terminal missile velocity.
