Cooperative guidance for multiple interceptors based on dynamic target coverage theory

A cooperative guidance law is developed for multiple interceptors to intercept multiple high-speed maneuvering targets cooperatively. Since the existence of background noise, uncertainties of the targets and low detection accuracy of the interceptors, only a dynamic region describing the location of targets by a probability density function can be obtained. A framework of cooperative detection is given to improve the detection accuracy owing to information sharing between interceptors. Based on dynamic target coverage theory, the reachable sets of the interceptors are positioned to cover the target dynamic region as much as possible, such that the probability of interception is maximized.
