Bio-inspired Evasive Movement of UAVs based on Dragonfly Algorithm in Military Environment

Abstract

Applications of unmanned aerial vehicles (UAVs) in the military environment have become popular because they requireminimum human contribution and can avoid accidents during missions. UAVs are employed in various missions such asreconnaissance, observation, aggression, and protection. Consequently, counter-measures, known as anti-drone technologies,have been developed as well. In order to protect against threats from anti-drone technologies and enhance the survivability ofUAVs, this study proposes an evasive measure. The proposed bio-inspired evasive maneuver of a UAV mimics a dragonfly’sirregular flight. The unpredictable UAV movement is able to confuse enemies and avoid threats, thereby enhancing the UAV’ssurvivability. The proposed system has been implemented on a commercial UAV platform (AR Drone 2.0) and tested in a realenvironment. The experiment results demonstrate that the proposed flight pattern has larger displacement values compared to aregular flight maneuver, thus making the UAV’s position is difficult to predict.
