Adaptive Target Tracking with Time-Varying Formation Radius

This paper introduces a novel adaptive guidance law to address active target tracking of multiple agents system. where multiple followers construct a circular formation with time-varying formation radius. The relative ranges between multiple followers and a target, the follower-target relative velocity components along the line-of-sight and the follower target relative velocity components normal to the line-of-sight can be regulated to early designed ones by adaptive parameters of the guidance law, while all followers coordinate their motion to maintain a circular formation whose center pursues the active target. Numerical simulations with the comparisons demonstrate the effectiveness and the superiority of the proposed method,
