Virtual Target Approach to Multi-Threat Guidance and Weapon-Target Assignment
Abstract
The proposed research will tackle the problem of integrating guidance with weapon target assignment (WTA) in a multi-on-multi interception engagement. In order to defeat, with maximum effectiveness, a multi-threat attack using a group of interceptors, it might be needed to use excess interceptors sent in a separate wave so as to serve as backup for unsuccessful intercepts of the first wave. Due to timing constraints it will be necessary to have the capability of reassigning, at least, these excess interceptors during the flight, that is to use dynamic WTA. Since reassignment might negatively affect guidance performance, the guidance algorithm has to a priori take into account the possibility of reassignment. It is envisaged to assign and guide some of the interceptor team members to moving and maneuvering virtual targets and perform the dynamic WTA, to actual and virtual targets, each time new information enters the system, e.g. a successful or failed intercept by a team member. We expect to develop a comprehensive integrated guidance and WTA approach, consisting of the trajectories for the virtual targets as well as a dynamic WTA strategy. We will seek optimal guidance for the virtual targets and dynamic WTA algorithms for the excess interceptors of the second wave, that together will provide the best hedging against failed intercept by the team members of the first wave.
