The first results of a novel 93 GHz airborne imaging radiometer

A 93 GHz conically scanning dual-channel (H&V) imaging radiometer has been built at the Helsinki university of Technology (HUT). The system has been designed for the Bell Jetranger helicopter, but can also be installed aboard the HUT remote sensing aircraft. The new features of the compact instrument are its ability to follow any feasible conical scan path, the airborne liquid nitrogen cooled cold calibration load as well as a flat panel color display providing a real-time false colour image and video image window. The very first experiences of the instrument are promising, and some of the data measured so far are presented.
