Sentences with phrase «radar interferometry»
Radar interferometry is an advanced technique that uses radar waves from satellites to measure changes on Earth's surface. It helps us understand movements such as earthquakes, ground subsidence, and glacier melting by comparing radar images taken at different times. It can detect even subtle changes in the landscape, allowing scientists to monitor and analyze environmental shifts more effectively. Full definition
