Detection, direction finding and localization of selected radio emissions with swarm technology

摘要

Due to the dynamic growth of applying civilian and military unmanned aerial platforms, a large saturation of the airspacewith this type of objects is observed. There are many problems associated with this, among which there are thefollowing: lack of systems informing about the location of other flying objects and violations of protected areas byunauthorized flying platforms. In this paper the concept of direction finding and localization of radio emissions using theUnmanned Aerial Vehicles based on the idea of a hierarchical “swarm” is presented. It is also discussed the UAVdetection methods taking into account the specific features of detected radio signal and selected aspects related to thefunctioning of UAS. Geolocation techniques are presented and one of them, dedicated to direction finding sources ofradio emissions, is indicated as preferred. Additionally, relevant mathematical formulas for geolocation method areproposed.
