Instrument details
Acronym IMR
Full name Interferometric Microwave Radiometer
Purpose To measure ocean salinity
Short description

An L-band interferometric radiometer system with a Y-shaped antenna array. Uses the interferometric aperture synthesis radiometry. In 1-D IMR, the interferometric synthetic aperture technique is applied only in the cross-track direction, resulting in higher resolution compared with the coarser along-track direction determined by the real antenna aperture.
