Interferometric synthetic aperture radar, abbreviated InSAR (or deprecated IfSAR), is a radar technique used in geodesy and remote sensing.This geodetic method uses two or more synthetic aperture radar (SAR) images to generate maps of surface deformation or digital elevation, using differences in the phase of the waves returning to the satellite [1] [2] [3] or aircraft.
InSAR can provide accurate (millimeter-level) ground displacement fields for large areas over hundreds of kilometres. [1] This technique uses two synthetic aperture radar images of the same area acquired at different times to measure surface motion between those times. [1]
A radio telemetry wireline extensometer monitoring slope deformation. Deformation monitoring (also referred to as deformation survey) is the systematic measurement and tracking of the alteration in the shape or dimensions of an object as a result of stresses induced by applied loads.
An inclinometer sensor's true or absolute accuracy (which is the combined total error), however, is a combination of initial sets of sensor zero offset and sensitivity, sensor linearity, hysteresis, repeatability, and the temperature drifts of zero and sensitivity—electronic inclinometers accuracy can typically range from ±0.01–2 ...
RADARSAT-2 is a Canadian Space Agency (CSA) Earth observation satellite. It launched on 14 December 2007 aboard a Starsem Soyuz-FG rocket from Baikonur Cosmodrome , Kazakhstan . [ 1 ] The spacecraft is owned by MDA (formerly MacDonald Dettwiler and Associates.) [ 2 ]
