beam-rider guidance[′bēm ‚rīd·ər ′gī·dəns]
A system for guiding aircraft or spacecraft in which a craft follows a radar beam, light beam, or other kind of beam along the desired path. Also known as beam bracketing; beam-climber guidance.
A guidance system in which the equipment aboard the missile enables it to sense its location relative to a radar beam and correct its course, seeking out and following the path made by a radar beam. The missile is gathered in the beam and is guided onto the target continuously by the radar beam locked onto the target. Also called beam-climber guidance.
