What is INSAR Full Form, Meaning, And Definition

On this page, We are going to learn about the full form of INSAR and the meaning of INSAR, As well as the meaning, definition, abbreviation, and acronym for INSAR in different categories. So you should read this post till the end.

The Full Form of INSAR: Interferometric Synthetic Aperture Radar

Insar Stands for Interferometric Synthetic Aperture Radar. InSAR is a land survey technology. that is used to detect and measure displacement earth’s surface or for mapping ground deformation in land surface altitude. InSAR helps to detect, measure, and monitor changes in the earth’s crust.

How does InSAR work?

in 2002 European Space Agency (ESA) launched the ENVISAT satellite for measurements of the atmosphere, ocean, land, and ice. InSAR technology used multiple multiple radar image pairs to find the displacement earth’s surface.

Actually, Remote sensing satellites, collect SAR imagery to transmit microwave energy to the Earth’s surface and record the amount of that energy that is backscattered.

What is InSAR used for?

  • High Precision: ability to detect  1 – 2 mm of displacement per year
  • Large Area Coverage: images (areas of analysis) that are 1500+ km² each
  • Dense Data Coverage: typically generate tens of millions of data points per area of interest
  • Remote Sensing: no ground instruments or in-person inspections required
  • Full Site Monitoring: often detects displacement in areas of unknown risk
  • Measurement Frequency: updated displacement measurements after each satellite revisit (typically every 2 – 12 days) source
