One typical application of unmanned aerial vehicles (UAVs) is made for the mission of circumnavigating and tracking ground targets, and how to complete the tracking task with limited sensor information remains a hotspot of current research. This paper develops a guidance law which relies only on distance measuring sensor, and does not need traditional bearing signal and location of UAV or ground target. A Lyapunov function is derived to prove the stability of the proposed guidance law. This guidance law is extended to the tracking of moving ground target with constant and time-varying speed. Comparing with existing ones, this guidance law is superior with simpler structure (only one parameter) and more reasonable guidance strategy. Simulation results show that the proposed guidance law can accomplish stable tracking of stationary and moving ground targets.
