Abstract

A brief overview of digital signal processing for infrared linescan imagery is presented. The need for digital signal processing arises from the desire to maintain high-quality imagery throughout the processing chain from sensor through data link to real-time display. Digital processing allows simple hardware to perform complex imagery manipulations including bandwidth compression, dynamic range control and automatic target screening. Digital processing also allows a real-time CRT display to be interfaced with infrared linescanners which generate enormous instantaneous data rates. Automatic aids to imagery interpretation and the simultaneous presentation of data from other sensors are also facilitated through digital processing. Recent developments at Honeywell in these areas are presented to show how airborne reconnaissance is adapting to the needs of the immediate future.
