A fuzzy guidance law for vertical launch interceptors

A fuzzy logic-based guidance design for longer engagement in time and beneficial interception attitudes is investigated and proposed here. The integrated fuzzy logic-based guidance scheme consisting of vertical, midcourse and terminal guidance phases can intercept the target from diverse aspects. The engagement strategy in the vertical guidance phase includes general vertical launch to handle the case of longer engagement ranges, and vertical launch with back turn (BT) to handle shorter engagement ranges. Numerical experimental results show excellent engagement performance and defensible volumes.
