Center Independent Research & Development: GSFC IRAD

Wideband low frequency radiometer: PolarRad

Completed Technology Project

Project Introduction

We propose to develop a wideband radiometer that would operate at P- and L-band frequencies. Experiments have shown the utility of brightness temperature measurements from 500-1400 MHz for enabling sea ice thickness to greater thicknesses, sensing of temperature information deep within ice sheets, improved sensing of sea salinity in cold waters, and enhanced sensitivity to soil moisture under vegetation canopies. This IRAD supported the development of the low frequency wideband radiometer for a future Earth Science mission.
