Abstract
The problem of developing an on-board signal processor which meets stringent power and performance constraints applicable to space-based mosaic sensors is addressed. A large sensor system concept is used to derive an example power budget. Speed power product requirements as derived from the example power budget are used to evaluate applicable LSI technologies in terms of their present and projected performance. The success of a given signal processor design in meeting the requirement of low power will depend on LSI technology, algorithms, their implementation, and the overall processing strategy. A signal processing concept that makes use of reconfigurable pipeline elements is introduced and discussed in terms of its applicability to low-power signal processor implementations. Particular attention is given to operational strategies that include segmented field-of-view processing for target classes, low duty cycles achieved through multiple sampling intervals, dynamic range compression, quick/long-look stare periods, and dual resolution.
