Pulse LengthThe linear distance in range occupied by an individual broadcast from a radar. Also called the pulse width. | |
Pulse Pair ProcessingNickname for the technique of mean velocity estimation by calculation of the signal complex covariance argument. The calculation requires two consecutive pulses. | |
Pulse Repetition FrequencyThe number of broadcasts by a radar per unit time. A.K.A: PRF | |
Pulse Repetition TimeThe time elapsed between successive broadcasts by the radar. Also called Pulse Interval. A.K.A: PRT | |

Radial VelocityComponent of target motion parallel to the beam axis. Also known as Doppler velocity. | |
Rainfall rate estimation | ||
Range binDiscrete element along a single radial of radar data at which the received signals are sampled. Range bins from POLDIRAD data are spaced at multiples of 150 m intervals. See also sample volume. | ||
Range FoldingApparent range placement of a multiple return. A multiple return appears at the difference of the true range and a multiple of the unambiguous range. | |
Range Height IndicatorDisplay on which radar signals are shown with height as the vertical axis and range as the horizontal axis, forming a vertical cross section of a cloud or precipitation system. | ||
