Application of Polynomial Trend Removal for Suppression of Doppler Clutter in Drone Surveillance Radars

The paper presents the results of studies devoted to a new approach for suppression of Doppler-spread clutter occurring in a drone surveillance radar. The proposed approach is based on application of the technique using polynomial trend removal. This technique is characterized by relatively effective computational complexity, allowing for implementation in real-time radiolocation signal processing. The results of field experiments with a drone surveillance radar, presented also in the paper, confirmed the efficiency of the proposed method for the Doppler-spread clutter suppression as well as its computational effectiveness.
