Radar altimeters employ electromagnetic signals to determine the distance between the instrument and a surface. This principle allows for high-precision height determination, making radar altimeters invaluable in various applications. Precise measurements are achieved through the analysis of the time delay between transmitted and received signals.

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
