The airborne EMIRAD L-band radiometer system

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


This paper describes the EMIRAD L-band radiometer, developed in support of the ESA/SMOS mission. The instrument is a fully polarimetric, dual antenna system, built with special focus on antenna accuracy, receiver stability, and detection and mitigation of radio frequency interference (RFI). The EMIRAD system has been installed on three different airborne platforms for measurements of sea surface signatures and salinity, soil moisture, and the homogeneity of the Antarctic SMOS calibration site. The installations are shown in the paper, and some major results for ocean and ice observations are given.
