The 93 GHz conically scanning dual-channel Airborne Imaging Radiometer, AIR-93, was completed at the Helsinki University of Technology in April 1995. It was designed for Bell JetRanger platform, but modified to be compatible with the HUT remote sensing airplane in few weeks after the completion. Test and service flight experiences aboard both platforms brought up improvement ideas, whose realization was considered easier aboard the HUT airplane. The new features include (a) rebuilding the electronics unit,(b) the use of an attitude-dGPS instrument to produce gyro data for radiometer beam active stabilization, (c) an improved version of the airborne, liquid nitrogen cooled cold calibration target, and (d) the digital, computationally stabilized, position oriented optical comparison image system. 9 refs., 7 figs., 1 tab.
