Abstract :
Inverse synthetic aperture radar (ISAR) images of a windmill are presented. In-situ measurement data of an 18- blade windmill are collected using an ultra-wideband radar. The measured signatures are compared to simulation results based on physical optics. The backscattering phenomenology is examined in the sinogram, spectrogram, and ISAR image domains. In addition, a composite image is generated from multiple ISAR snapshots to reveal the entire windmill structure.
