Precise altimetry refers to the accurate measurement of height or elevation. Radar technology plays a crucial role in achieving this precision. By emitting electromagnetic waves and analyzing the time it takes for these waves to return from a target, radar systems can determine the distance between the sensor and the target, thus enabling precise altitude measurements. Radar altimeters are widely employed in various applications, including aviation, meteorology, and surveying. For aircraft navigation , radar altimeters provide critical information about the aircraft's height above the ground, ensuring safe landings and takeoffs. In meteorology, radar altimetry helps analyze ocean currents . Additionally , radar-based altimetry is essential for accurate topographic mapping and geological surveys.
