Sentences with phrase «radar satellites»
"Radar satellites" refers to satellites equipped with radar technology. These satellites use radio waves to gather information and create detailed images of the Earth's surface. They can be used to monitor and study various features, such as weather patterns, land and water surfaces, and even detect changes in the Earth's topography. Full definition
