www.ijsr.netdegrades the quality of the active radar and synthetic aperture radar (SAR) images.[6] Speckle noise in conventional radar results from random fluctuations in the return signal from an object that is no bigger than a single image-processing element. It increases the mean grey level of a …
Sentinel-1 Toolbox TOPS Interferometry Tutorial
step.esa.intInterferometric synthetic aperture radar (InSAR) exploits the phase difference between two complex radar SAR observations taken from slightly different sensor positions and extracts information about the earth’s surface. A SAR signal contains amplitude and phase information. The amplitude is the strength of the radar
