Polarimetric Met Index
polarization
Polarization of electromagnetic radiation is defined by the direction of the electric
field. In traditional weather radars only horizontal polarization is used. In a dual-
polarization weather radar, both horizontal and vertical polarizations can be
transmitted and received simultaneously.
PPP
Poly-Pulse Pair. An RVP signal processing mode based on pulse pair correlations. See

FFT (page 468)
RAW product
Spherical coordinate data product obtained directly from the raw ingest data. The
data are stored in compressed format so they can be recorded on tape or sent to a
workstation for further processing.
RCP
Radar Control Processor. Takes care of, for example, antenna movements.
RDA
Radar Data Acquisition software used in RVP900
RF
Radio frequency
RPG
radar product generator
RS

RVP900
Digital IF Receiver and Signal Processor. A floating-point programmable signal
processor which directly samples the IF signal from a radar.
RX
Receiver
signal processor
A programmable device for digitizing and processing video signals from the radar
receiver.
