Radar Interferometry

Radar Interferometry is a technique that uses overlapping radar signals to measure tiny changes in the Earth's surface. By comparing the phase differences of radar waves reflected from the ground at different times, it can detect movements like land subsidence, earthquakes, or volcanic activity with high precision. This method works even through clouds and in darkness, making it valuable for monitoring environmental and geological changes over large areas. Essentially, it transforms radar data into detailed, accurate measurements of surface deformation, helping scientists understand and track dynamic processes on the planet.
