Abstract:
MASTR (the Multi-Application Smallsat Tri-band Radar) is a SmallSat instrument concept capable of electronic scanning, Doppler velocity measurement, and polarimetry at Ku/Ka/W-band frequencies. These capabilities allow MASTR to work as a cloud and precipitation radar, an altimeter (targeting sea ice height and snow depth) or as a scatterometer (in a spinning configuration). Consequently, MASTR has the potential to support several of NASA's Earth science programs including Cloud and Radiation, Precipitation Measurement, Cryospheric Sciences, Climate Variability and Change, and Physical Oceanography. AirMASTR, the airborne prototype of MASTR, is currently under development with a target deployment in fall 2019. This instrument's architecture uses Active Linear Array Feeds (ALAFs) to feed a parabolic-cylindrical reflector. A modular design allows MASTR to grow in size without significant redesign. MASTR was conceived to enable significantly smaller instruments that meet several science needs using a modularized architecture that is flexible and can adapt to multiple measurement objectives.
