This paper presents investigations on a radar sensor concept tailored for bird observation in direct proximity of wind turbines. The task is to monitor birds which live in the surrounding of a wind farm in order to stop concerned wind turbines in case of probable collisions. Experiments were performed leading to a proper characterization of the dynamic radar echoes of birds and wind turbines. A concept...
Recent critical instances have demonstrated the demand for an effective way of detecting and classifying small Unmanned Aerial Vehicles (UAVs) as they pose a serious threat in civil security. We present results of radar measurements with a one channel continuous wave system at Ka band aiming at classifying UAVs through a detailed micro-Doppler analysis. High-sensitivity measurements of different UAVs...
The use of small unmanned aircraft systems (sUAS) or ‘drones’ is increasing rapidly. This has many positive benefits but also comes with safety and security risks that must be managed. These include UAS collision with manned aircraft, UAS collision with people on the ground and wider security threats such as the protection of personal privacy and terrorist activity. The “Gamekeeper” radar has been...
Unmanned Aerial Systems (UAS), commonly referred to as drones, are rapidly proliferating bringing about new challenges for security and safety. The reason being their small size and ability to fly low in a highly irregular manner makes them particularly difficult to detect with conventional wide-area surveillance sensors such as a scanning radar. Here, we use staring radar that employs a 2-D antenna...
