HIWRAP

High Altitude Imaging Wind and Rain Airborne Profiler

HIWRAP

Remote Sensing Solutions (RSS), NASA Goddard Space Flight Center (GFSC) and the University of Massachusetts (Umass) teamed through the NASA Instrument Incubator Program to develop the High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) for deployment on the NASA Global Hawk and other high altitude aircraft. The HIWRAP is a solid-state conical scanning, dual-frequency, dual-beam Doppler radar. It acquires volume and surface backscatter profiles simultaneously at Ku and Ka-band wavelengths and two incidence angles (30 an 40 degrees). From these measurements it maps the 3-dimensional tropospheric and atmospheric winds, ocean vector surface winds and precipitation field in and around tropical cyclones and severe ocean storms.

To achieve high sensitivity and overcome range-Doppler ambiguities, HIWRAP uses a novel transmit waveform (frequency diversity pulse compression) developed through a RSS NASA STTR project. HIWRAP has been deployed on the Global Hawk in the NASA Genesis and Rapid Intensification Processes (GRIP) experiment and on the NASA ER-2 in support of Global Precipitation Measurement (GPM) Mid-Latitude Continental Clouds Experiment (MC3E). HIWRAP is to participate on the Global Hawk in the multi-year hurricane study (HS3).
