A Study on Improving the Sensitivity of High-Precision Real-Time Location Receive based on UWB Radar Communication for Precise Landing of a Drone Station

Drone stations are increasingly being applied to enhance the mission capabilities of drones. The drone’s station landing occurs in a limited space. A relative position communication signal between the drone and the station is required. Strong, precise control over communication signal interference is required. In this paper, we describe a filter processing method for position signal processing. In consideration of the anchor position and installation angle of the UWB module of the drone station, nine performance test cases were proposed. As a result of the performance test, high position accuracy output was confirmed when considering the result of minimizing signal shading and beam pattern direction with excellent reception sensitivity. A performance test was conducted using the developed drone station, and the landing performance was confirmed with a precision of within 20 cm.
