The signal processor system for the NASA Dual-Frequency Dual-Polarized Doppler Radar

Abstract

• D3R is the Ground Validation radar for Global Precipitation Measurement program [Chandrasekar et. al., “Scientific and engineering overview of the NASA Dual-frequency Dualpolarized Doppler Radar (D3R) system for GPM ground validation”, IGARSS’2010]. • Currently operational and has been deployed for field campaigns. • Sensitivity: -10 dBZ at 15 km to enable snow measurements. • Maximum unambiguous range = 30 km. • Precipitation measurements at frequencies. Ku-band: 13.91±.25GHz, Ka-band: 35.56±.25GHz. • Dual linear polarizations with capability for both polarization agility and diversity. Figure 1. D3R deployed at ARM Southern Great Plains site during GPM Midlatitude Continental Convective Clouds Experiment (MC3E) (05/28/2011). This was the first mechanical deployment of D3R in a field campaign. D3R Waveform Design
