Fast 3D-CFAR for Drone Detection with MIMO Radars

In the present paper a novel fast 3D constant false alarm rate (CFAR) detection algorithm is presented and applied to 3D MIMO radar data taking into account azimuth, range and doppler information. The algorithm is designed to minimize the computation effort and its performance is investigated for drone detection in sparse scenarios. For a first experimental drone flight the algorithm significantly improves the detection compared to 2D-CFAR.
