Mixed Strategies for the Interception of Blind Highly Maneuvering Targets
Abstract
This Annual Technical Report, being the final report on a long-term investigation, has two objectives. It describes the technical effort performed in the last year and also summarizes the results of the entire (two and half years) investigation with an outline of the directions for future research. Most missile guidance laws were developed using linearized two-dimensional models assuming constant speed and maneuverability. Simulation results demonstrated that linear guidance theory, based on such a model, couldn't predict the miss distance in an actual real world time-varying missile/target scenario, such as the interception of a reentering Tactical Ballistic Missile. An earlier Interim Report described the first attempt to extend the linear guidance model to include time-varying speed and maneuverability. In this report the generalized time-varying linear pursuit-evasion game model is developed. Based on this model a modified guidance law with improved homing performance is derived. The predictions of the time-varying linear model are validated by simulations of a realistic Ballistic Missile Defense scenario. Summarizing the more than two years investigation, it can be stated that its objective to gain an "understanding how key parameters in the models of the interceptor missile and of the target affect the outcome of an engagement" has been accomplished at least in a deterministic (noise free) environment. The affects of time-varying parameters and nonlinear kinematics were separately analyzed. Extension of the investigation to an environment corrupted by measurement noise, having been out of the scope of the reported effort from the outset, seems to be the appropriate direction for future research.
