1. An airborne radar in which the beam from phased array antennae changes form and direction according to electronic velocities or speeds.
2. An airborne radar that uses a phased-array antenna which changes radar-beam forms and beam positions at electronic speeds.

When combined with digital processing of the radar returns, it can simultaneously provide such functions as beacon-locating, forward-looking mapping, navigation updating, terrain avoidance, and terrain-following in manned strategic bombers and other aircraft.
