Bragg scattering of power lines based on W-band SAR

With the advantage of fast imaging speed, video synthetic aperture radar (ViSAR) is able to monitor small targets in key areas continuously. W-band is relatively high band to realize video imaging, the Bragg scattering characteristics also create conditions for the imaging and detection of shadows for power lines. This paper reports the video imaging results of a small UAV-borne W-band SAR on power lines and analyzes the relationship to incident angles.
