Wideband low frequency radiometer: PolarRad

Low frequency wideband microwave radiometer operating at P- and L-band frequencies will address multiple water cycle variables: (1) Ice sheet temperature, (2) Sea ice thickness, (3) Cold water salinity, and (4) Root-zone soil moisture. This project addressed the engineering challenges in addition to the wide operating bandwidth include detection and mitigation of radio frequency interference (RFI) which is expected at these frequencies. A low frequency wideband radiometer operating at 0.5-2 GHz was designed that would address the above science variables.

The purpose of the Goddard Space Flight Center’s Internal Research and Development (IRAD) program is to support new technology development and to address scientific challenges.  Each year, Principal Investigators (PIs) submit IRAD proposals and compete for funding for their development projects.  Goddard’s IRAD program supports eight Lines of Business: Astrophysics; Communications and Navigation; Cross-Cutting Technology and Capabilities; Earth Science; Heliophysics; Planetary Science; Science Small Satellites Technology; and Suborbital Platforms and Range Services.

Task progress is evaluated twice a year at the Mid-term IRAD review and the end of the year. When the funding period has ended, the PIs compete again for IRAD funding or seek new sources of development and research funding, or agree to external partnerships and collaborations.  In some cases, when the development work has reached the appropriate Technology Readiness Level (TRL) level, the product is integrated into an actual NASA mission or used to support other government agencies. The technology may also be licensed out to the industry.

The completion of a project does not necessarily indicate that the development work has stopped.  The work could potentially continue in the future as a follow-on IRAD; or be used in collaboration or partnership with Academia, Industry, and other Government Agencies.
