Abstract

This paper proposes a new guidance law inspired by hawk�s behavior in attacking its prey. Our analysis of experimental data available in the literature from studies carried out in this direction shows that hawks increase their speed when the prey does not maneuver and decrease its speed when the prey maneuvers. This observation was used to design a guidance law in which the pursuer vehicle uses a combination of longitudinal acceleration and conventional proportional guidance law against an evader having both maneuvering and non-maneuvering phases. This approach helps the pursuer to intercept the target with lesser control effort than pure proportional navigation guidance law. This new guidance law also performs well in bounded lateral acceleration scenarios for maneuvering targets. The idea can be effectively implemented in interceptor drones since drones can control their speeds © 2022, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.
