PSInSAR:
Persistent Scatterer Interferometric Synthetic Aperture Radar (PSInSAR) is a remote sensing technique that uses radar signals from a satellite to accurately measure ground displacement. PSInSAR is an improved and more accurate analysis algorithm compared to the InSAR method.

Introduction
  • "Persistent Scatterer Interferometric Synthetic Aperature Radar (PSInSAR) is a remote sensing method which bounces satellite radar signals off of naturally occurring permanent scattering points. Features such as roof tops, bridges, dams, water pipelines, antennae, large rock outcrops, and other prominent natural features make good persistent scatterers. The precise position of each scatterer in relation with other scatterers can be recorded. Using this technique the motion of each scaterer structure can be very precisely tracked and ground deformation can be determined.'"`UNIQ--ref-00000000-QINU`"'" cannot be used as a page name in this wiki.

Use in Geothermal Exploration
  • "PSInSAR is useful for monitoring and precisely measuring the movement of a geothermal area over time. Changes in the underground water levels, pressures, and temperatures due to geothermal utilization can lead to changes on the surface. Subsidence or uplift of a geothermal area before and after utilization can be monitored and for geothermal areas located in fault zones lateral movement along fault lines in the area can be monitored. With the PSInSAR method ground movement and movement rates can be calculated with millimeter accuracy.'"`UNIQ--ref-00000001-QINU`"' PSInSAR methods are advantageous compared to conventional GPS methods because a much larger area can be monitored and no ground equipment is needed.'"`UNIQ--ref-00000002-QINU`"'" cannot be used as a page name in this wiki.

    Best Practices
    The given value was not understood.
     PSInSAR is a useful technique for monitoring the effects of fluid injection and extraction on surface deformation at geothermal areas. This method can also be used for detection of active faults in a geothermal area. PSInSAR is an accurate and cost-effective method. It is a useful method in agricultural areas, where conventional methods fail such as in Imperial Valley.[3] PSInSAR can be applied to geothermal exploration and the management of producing fields.[2]
     
    Potential Pitfalls
    The given value was not understood.
     PSInSAR cannot be used in highly vegetated areas unless manmade scatterers are built. Also, time measurements are limited to the intervals in which the satellites orbit.[1]
