The C-Band Scanning ARM Precipitation Radar is a dual-polarization Doppler weather radar that operates in a simultaneous transmit and receive (STAR) mode, splitting the transmit signal so that power is transmitted on both horizontal and vertical polarizations at the same time. The C-SAPR can also transmit on a single polarization (horizontal or vertical) and measure linear depolarization ratio (LDR).
In addition to the first three Doppler moments (reflectivity, radial velocity, and spectra width), the C-SAPR also provides differential reflectivity, correlation coefficient, and specific differential phase. The dual-polarization variables enable the provision of rainfall rate estimates and identification of precipitation types.
