The Airborne Second Generation Precipitation Radar (APR-2) is a cross-track scanning, dual-frequency airborne precipitation radar. It measures radar backscatter from rainfall to provide measurements of reflectivity, Doppler velocity, and linear depolarization ratio (LDR). APR-2 operates at 13.4 GHz and 35.6 GHz and has a pulse repetition frequency (PRF) of 5000 Hz. At a flight altitude of 11,000 feet, it has a horizontal resolution of 730 m at 13.4 GHz and 920 m at 35.6 GHz. APR-2 has a vertical resolution of 60 m and a ground swath width of 10 km.
