R
RADARAn acronym for RAdio Detecting And Ranging [18]. |
RADAR ALTIMETERAirborne radar that measures the distance of the aircraft above the ground [18]. |
RADAR BEAMThe space in front of a radar antenna where a target can be effectively detected or tracked. Defined by areas that contain half or more of the maximum power transmitted [18]. |
RADAR DETECTORA detector that, in its simplest form, only needs to be capable of producing an output when RF energy (reflected from a target) is present at its input [12]. |
RADAR DISTRIBUTION SWITCHBOARDAn electrical switching panel used to connect inputs from any of several radars to repeaters (indicators) [18]. |
RADAR MILETime interval (12.36 microseconds) for RF energy to travel out from a radar to a target and back to the radar; radar nautical mile [18]. |
RADAR TEST SETA combination of several test circuits and equipment used to test various characteristics of a radar [18]. |
RADIATION FIELDThe electromagnetic field that radiates from an antenna and travels through space [10]. |
RADIATION LOSSESThe losses that occur when magnetic lines of force about a conductor are projected into space as radiation and are not returned to the conductor as the cycle alternates [10]. |
RADIATION PATTERNA plot of the radiated energy from an antenna [10]. |
