Several hot issues and challenges in terminal guidance of flight vehicles

With the development of the science and technology for national security and defense, new combat scenarios, new application requirements and especially new techniques come up which bring problems and challenges for terminal guidance and control of flight vehicles. The current requirements and new threats are analyzed in this paper. Several hot issues are discussed, including guidance and control under multi-source information, cooperative guidance and control of multiple flight vehicles, guidance and control under special limits, as well as integrated design and evaluation of guidance and control system. Additionally, the key problems, potential future directions and prospects are summarized.
