Paper Abstract

The Advanced Solidstate Array Spectroradiometer (ASAS) is a multispectral pushbroom scanner with 32 channels extending from 400 to 850 nm. It is built around a 32 by 512 element charge injection device (CID) array with enhanced sensitivity in the blue. It has twelve-bit output with variable gain and offset in the pre-amp and a framing rate which can be varied from 3 to 64 frames per second. The CID detector and the camera head electronics were designed and built by General Electric. The NASA Johnson Space Center (JSC) designed and built the data storage processor electronics. The optics were taken from an older system built by TRW for NASA. Contracting and coordination for the project was done under a Naval Ocean Systems Center (NOSC) program for ocean remote sensing, The completed system has been flown, tested, and calibrated and has been undergoing noise reduction analysis and modification at the NASA Goddard Space Flight Center. Details on the design, fabrication, and functioning of the CID array, the camera module electronics, and the data processor are given as well as an analysis of the scanner's performance and noise characteristics.
