PURPOSE: To improve the S/N of infrared data of architecture and to reduce the band width of output data from an infrared focal face array by two digits. CONSTITUTION: A programmable focal face signal processor digitally executes all the analog/digital conversion, non-uniformity correction and gamma line spike compensation on a single silicon substrate inside a Dewar vessel. The architecture improves the S/N of focal face array data by supporting time delay integration and spatial filtering. The processor has a programmable coefficient which can be changed or erased even when operating.
