ARMAR
Airborne Rain Mapping Radar

The Airborne Rain Mapping Radar (ARMAR) is an airborne Ku-band Doppler radar developed by the Jet Propulsion Laboratory (JPL). It was developed to simulate Tropical Rainfall Measuring Mission (TRMM) satellite mission for algorithm development and calibration. ARMAR operates at the 13.8 GHz frequency to measure the return power of microwave energy to calculate the velocity and reflectivity. It also can be operated as a radiometer to measure brightness temperature. ARMAR typically scan across track at 20 degrees angles, but also has the ability to operate at a fixed angle. ARMAR has a horizontal resolution of 800m and a swath width of 9km at flight altitude of 12km.
