Özet: Remote sensing is the art of acquisition of information about any objects (such as the Earth) without making any physical/close contact. Remote sensing has many vital civilian and none-civilian applications. Interferometric Synthetic Aperture Radar (InSAR) is a radar technique used in geoscience and remote sensing to measure the Earth surface deformation from 800 km above the Earth. In particular, Permanent/persistent/point-like Scatterer Interferometry (PSI) is a powerful remote sensing technique, which is able to measure the deformation on the Earth’s surface over temporal baselines. This technique was developed to estimate the temporal characteristics of the Earth’s deformation rates from multiple radar images acquired over time (series). This paper reviews InSAR and PSI techniques, and explains the current state of the art and potentials of the available radar remote sensing techniques. One case study is examined, pertaining to well-known deformation problem in the Mexico City area.
