Abstract

The paper presents a Lyapunov vector field based guidance law for stand-off target tracking. The proposed vector field is based on a circulation parameter which is a function of the radial distance from the target. The resulting curvature is zero both at the center and far away from the stand-off circle. With respect to existing Lyapunov vector fields, the simulation results highlight two major advantages. Firstly, with a lower maximum curvature limit, the proposed method provides yable trajectories both inside and outside the stand-off circle. Secondly, tracking a stationary target using the proposed vector field presents a faster convergence. © 2017, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.
