Asynchronous Cooperative Guidance for Multiple Intercepting Flight Vehicles: A Dynamic Target Coverage Approach

In this paper, a problem how multiple intercepting flight vehicles intercept a high-speed maneuvering target is considered. Due to the uncertainties of the target caused by the background noises and low detection accuracy of the intercepting flight vehicles, we use a dynamic distribution to describe the location of target. Therefore, the cooperative intercepting problem is transformed into a problem to cover a known dynamic distribution. In order to deal with the dynamic target coverage problem more effective, an asynchronous cooperative way is considered in this paper. Based on dynamic target coverage theory, a finite time cooperative guidance law is developed, and with the cooperative guidance law the reachable sets of the intercepting flight vehicles can cover the target dynamic distribution as much as possible to maximize the probability of interception and guarantee collision avoidance.
