Unmanned aerial vehicle defense based on jamming suppression

Abstract

The number and scale of unmanned aerial vehicles (UAVs) are growing explosively, and the frequent occurrence of UAV intrusions poses a serious threat to national security and social stability. Therefore, it has become increasingly important to defend against UAVs and develop related defense technologies. In order to effectively defend against UAVs, it is necessary to interfere with their GPS/Beidou positioning and 2.4G communication technology, thus disrupting their positioning and communication and rendering them unable to function properly. This article designs and implements a continuous wave single tone narrowband interference, and tests its performance, achieving a power suppression effect that seriously interferes with GPS positioning and blocks communication.
