The ER-2 X-Band Doppler Radar (EXRAD) is a dual-beam X-band radar mounted on NASA’s ER-2 aircraft. It was originally designed for the Global Hawk but was later developed for the ER-2 to replace the ER-2 Doppler Radar (EDOP). EXRAD measures backscatter to determine radar reflectivity, Doppler velocity, and linear depolarization ratio to analyze the phase, orientation, size, and other properties of precipitation particles. EXRAD operates at 9.6 GHz and has a range resolution of 37.5 to 300 meters. It has a swath width of 28 km at an altitude of 20 km during scanning mode, with a typical sampling frequency of 0.25 seconds.
