Software Development for Collision Avoidance of a RPAS (Remotely Piloted Aircraft System) with use of a FMCW Radar

Abstract [en]

The unmanned aerial systems market experiences a growing demand for some years now. With increasingly unmanned systems in airspace the risk of encounter increases. More and more vehicles are entering the limited and regulated airspace. However, such have not yet been implemented consistently or not at all in the area of UAV. The result is an ever increasing risk of collisions in airspace. Solutions for minimizing the risk for a collision have to be found. The aim of this study is the commissioning and integration of a radar sensor in a UAV for collision detection and avoidance. For this purpose, an existing radar sensor is integrated in a UAV and validated in subsequent tests. The result is a solid and good visibility of large objects. House walls and any metallic objects can be detected in the flight path. An implemented tracker algorithm will track and recognize obstacles reliably. Organic obstacles still present a problem. It is, for example, problematic to detect trees because of the backscatter characteristics. There are several recommendations for improving a future system, e. g. with an extension of the systems internal and additional external sensors.
