A Classification Recognition Method of UAVs and Birds Based on a Fusion Measure with the VMD-Driven Model and Time–Frequency Spectrum Segmentation
To improve the classification and recognition ability of radar detection unmanned aerial vehicles (UAV) under low signal-to-noise ratio conditions, this paper propose a two-domain feature extraction method that combines variational mode decomposition (VMD)-based modal features with short-time Fourier transform (STFT)-b...
