  2. Radar altimeter - Wikipedia

    en.wikipedia.org/wiki/Radar_altimeter

    Radar altimeters are frequently used by commercial aircraft for approach and landing, especially in low-visibility conditions (see instrument flight rules) and automatic landings, allowing the autopilot to know when to begin the flare maneuver. Radar altimeters give data to the autothrottle which is a part of the Flight Computer.

    en.wikipedia.org/wiki/Altimeter

    Radar altimeter technology is also used in terrain-following radar allowing combat aircraft to fly at very low height above the terrain. After extensive research and experimentation, it has been shown that "phase radio-altimeters" are most suitable for ground effect vehicles, as compared to laser, isotropic or ultrasonic altimeters.

    The International Space Station (ISS) has long been used as a central satellite platform for other sensors, including Earth observation sensors. For example: LIS, SAGE III, TSIS-I, ECOSTRESS, GEDI, OCO-3, Diwata-1, and HICO. Jason-3: Active NASA and CNES: 2016 Radar altimeter used to monitor ocean surface height.

    The Cassini radar was a multimode system and could operate as Synthetic Aperture Radar, radar altimeter, scatterometer and radiometer. Sounding radars : these are low-frequency (normally, HF - 3 to 30 MHz - or lower) ground-penetrating Radars , used to acquire data about the planet sub-surface structure.

    The satellite carried a radar altimeter capable of measuring the distance from the satellite to sea surface with a relative precision of about 5 cm. The initial phase was an 18-month classified Geodetic Mission (GM) have a ground-track with a near-23-day repeat with closure to within 50 kilometers.
