Abstract:

	 Pushbroom spectral imaging (PSI) systems are frequently capable of generating much
more data than can be transmitted to the ground. Furthermore, extensive ground calibration
often impedes the full utilization of the data. These problems may be solved by application
of commercial, focal-plane-array technology which provides massively parallel processing
of each detector's signals. This processing can be programmable, occur in real time,
and include non-uniformity (gain and offset) calibration, digitization, and buffering.
The proposed innovation is a signal-processing, integrated circuit (IC) which will
enable PSI systems to generate higher data throughput and to be self calibrating.
	The Phase I effort consisted of requirements definition, electronics specification,
IC design, control unit specification, and planning of future work. This work showed
the feasibility of placing gain compensation, offset correction, and automatic detector
and readout electronics calibration circuitry, anti-aliasing filtering, and analog-to-digital
conversion on the focal plane on a per-channel basis to provide high performance
remote sensing capabilities for PSI systems. Preliminary designs for the critical
integrated circuit components have been completed and were tested using computer
simulation software.
