The key benefits of charge-coupled devices in space-borne scanning point-target detection/location systems are the potential impact for power, size, weight, and cost reduction. These advantages accrue from the capability for integrating several CCD signal processing functions onto a single substrate. This paper describes results of an effort which successfully demonstrated the monolithic integration of key CCD signal processing functions for a representative high-performance scanning surveillance sensor. The principal information required by the sensor for this application is the magnitude and two-dimensional centroid estimation of point targets. The key functions provided by the CCD signal processor are delay-and-add and focal-plane formatting for two-way scanned sensor, multiplexing, and two-dimensional analog centroid filtering. |
