This paper provides an overview of target tracking control for UAV formation. Multi-UAV cooperation is essential for efficient and safe completion of target tracking tasks, as compared to a single UAV. The task of UAV formation target tracking often involves flying in formation to the airspace near the target and achieving tracking around the target, which includes two core issues: formation control and target tracking. We summarize the latest results in formation control and target tracking control schemes, and provide recommendations for future research directions in this area.
