utilized up to this time in the first generation aircraft, the new system should include new sensors, developed and designed underthesponsorship ofthe German Ministry of Research andTechnology, Laser Fluorosen- sor and Multiple Frequency Microwave Radiometer which allow more thorough analysis of oil spills. This includes quantification of the spilled volume over range covering small dis- charges up to accidental events, and the classification of oiltypes. The Archimedesexercises offereda uniquechancetostudyradiometeroutputs inthe5GHzto 9GHz range for different types of oil and oil-water emulsions of varying thickness (up to several millimeter) during variety of realistic environmental conditions. series of findings resulted which, togetherwith some operational restraints was nowan ideal basis to define the basic requirements for radiometer of second generation: simultaneous measurements at several frequencies to reduce ambiguity problems during the determination of layer thickness $nd, above all, the oil volume; an error of volume estimation smaller than 5% is tolerated, selection of frequency bands with reference to possible interferences due to man made noise and registration of oil layer thickness in the 0.0 mm to 3 mm range, simultaneous registration of the sky radiation at least atthe highestfrequency band which is most sensitive with respect to variation of weather conditions, scan angleas largeas possibleto realizescanwidths comparabletothoseofconventional IR/UV line scanner 2 spatial resolution as high as possible under the proviso of the maximum tolerable dimen- '8 considerationoftypicalflightaltitudesof 3mtol0mandaircraftvelocitiesnear7m/ 2.
