Spatial–Frequency Domain Joint Learning With Shape Constraints for Fine-Grained Aircraft Detection in SAR Imagery

Fine-grained aircraft detection aims to detect aircraft and identify its subcategory, which is important for military reconnaissance and airport management. Compared with optical imagery, aircraft in synthetic aperture radar (SAR) images exhibit high azimuth sensitivity and discrete scattering chara...
