    en.wikipedia.org/wiki/Radar_altimeter

    The dipole antenna of a radar altimeter of 1947. A radar altimeter (RA), also called a radio altimeter (RALT), electronic altimeter, reflection altimeter, or low-range radio altimeter (LRRA), measures altitude above the terrain presently beneath an aircraft or spacecraft by timing how long it takes a beam of radio waves to travel to ground, reflect, and return to the craft.

    The XBQM-108 project was initiated in 1975 by the Aviation and Surface Effects Department of the U.S. Navy's David W. Taylor Naval Ship Research and Development Center. [1] [2] The project was intended to demonstrate the practicality of the 'Vertical Attitude Take-Off and Landing' (VATOL), or 'tailsitter' flight profile for remotely piloted vehicles, [2] as the Navy believed the increasing ...

    en.wikipedia.org/wiki/ADM-141_TALD

    The "ADM-141C ITALD" is similar to TALD, but is fitted with a Teledyne CAE-312 turbofan engine, which provides 0.78 kN (80 kgp / 177 lbf) thrust and was developed for a cancelled anti-radar cruise missile named "Tacit Rainbow". ITALD has a ventral intake for the turbofan, and a radar altimeter so it can maintain low-level flight at a specified ...
