Abstract :
The authors´ airborne multifrequency microwave radiometer system HUTRAD (Helsinki University of Technology RADiometer) is described. The system consists of a non-imaging subsystem and an imaging subsystem. The non-imaging subsystem operates at six frequencies between 6.8 and 94 GHz, with vertically and horizontally polarized channels at each frequency. Its main technical characteristics are close to those of the ESA MIMR (Multi-frequency Imaging Microwave Radiometer) instrument. The imaging subsystem operates at 93 GHz and is dual-polarized. HUTRAD is accommodated onboard the Helsinki University Technology research aircraft Shorts Skyvan
