Radar Range Equation (RRE): The radar range equation (rre) relates the range performance of a radar system to other radar components and their characteristics.
Radar Range: A measurement of the distance an object can be seen by radar based on the height of the antenna, the height of the object and atmospheric bending of the radar beam.
Range Bin: Discrete element along a single radial of radar data at which the received signals are sampled. Range bins from poldirad data are spaced at multipes from 150 m intervals. See also sample volume.
Range: (also 'driving range, practice range, practice tee') an area, separate from the golf course, designated for hitting practice balls
Range Finders: Markers in the lane that help the bowler determine the target line. There are two sets of such markers: ten dots located seven feet past the foul line and seven arrows arranged in a triangle . . . View Full Definition
Range Height Indicator (RHI): A range height indicator (rhi) is a radar display that represents the height of the target on the vertical axis, and uses the horizontal axis of the rhi to represent the target range.
