Abstract
THIS RESEARCH IS DIRECTED TOWARD IMPROVEMENT OF PRESENT SELF CALIBRATING, THERMOPILE BASED, CAVITY RADIOMETERS FOR USE IN RADIANCE MEASUREMENTS FROM EARTH VIEWING SATELLITE INSTRUMENTS. THE PRIMARY THRUST IS TO IMPROVE THE RESPONSIVITY OF THE DEVICE, AND MINIMIZE POSSIBLE THERMAL OFFSET SIGNALS WITHIN THE SENSOR. THE APPROACH INVOLVES REDESIGN OF THE THERMAL IMPEDANCE OF THE THERMOPILE ELEMENT AND OPTIMIZATION OF THE PLATING TECHNIQUE FOR THE JUNCTIONS. ADDITIONALLY THE MINIMIZATION OF THE EFFECTS OF THE THERMAL TRANSIENTS IN THE HEAT SINK AND THE BAFFLE/APERTURE ASSEMBLY WILL BE STUDIED. CONSIDERATIONS WILL BE INCLUDED IN THE DESIGN TO ALLOW THE SENSORS TO BE EMPLOYED IN A CONTIGUOUS ARRAY FOR USE IN A NON SCANNING EARTH RADIANCE INSTRUMENT.
