Abstract

A reduced Y-shape interferometric radiometer has been used to simulate the performance of MIRAS, the single payload of the ESA SMOS mission. The hardware has been designed according to initial MIRAS specifications using first versions of antennas, L-band receivers, digital correlators and calibration subsystems. A complete set of experiments to assess basic operation, calibration methods and instrument performance has been successfully carried out and is described in this paper.
