Researchers from Netherlands Organization for Applied Scientific Research Report Recent Findings in Microwave and Wireless Technologies (Classification of small UAVs and birds by micro-Doppler signatures)
By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Microwave and Wireless Technologies have been published. According to news reporting originating in The Hague, Netherlands, by VerticalNews journalists, research stated, "The popularity of small unmanned aerial vehicles (UAVs) is increasing. Therefore, the importance of security systems able to detect and classify them is increasing as well."
The news reporters obtained a quote from the research from Netherlands Organization for Applied Scientific Research, "In this paper, we propose a new approach for UAVs classification using continuous wave radar or high pulse repetition frequency (PRF) pulse radars. We consider all steps of processing required to make a decision out of the raw radar data. Before the classification, the micro-Doppler signature is filtered and aligned to compensate the Doppler shift caused by the target's body motion. Then, classification features are extracted from the micro-Doppler signature in order to represent information about class at a lower dimension space. Eigenpairs extracted from the correlation matrix of the signature are used as informative features for classification. The proposed approach is verified on real radar measurements collected with X-band radar. Planes, quadrocopter, helicopters, and stationary rotors as well as birds are considered for classification. Moreover, a possibility of distinguishing different number of rotors is considered. The obtained results show the effectiveness of the proposed approach."
According to the news reporters, the research concluded: "It provides the capability of correct classification with a probability of around 92%."
