WebDec 4, 2024 · Light Detection and Ranging (LiDAR) is a remote sensing method that works on the principle of radar, but uses light in the form of pulsed laser to measure variable distances to the earth. It is essentially a tool used to make extremely high resolution maps. The light pulses generate 3D information about the shape of the Earth’s surface. WebSep 1, 1996 · A processing technique for polarimetric synthetic aperture radar (SAR) data has been developed which produces profiles of terrain slopes and elevations in the azimuthal (or along-track) direction. This technique estimates the average shift in orientation angle of copolarization backscatter caused by azimuthal tilts of the scattering plane.
