Paper Abstract

Commercial frame grabber technology in IBM PC compatible computers has been adapted to allow direct digital input of infrared search and track data at rates of up to 10 mbytes per second, permitting real-time processing and display of false color thermal images. Examples of single frame displays and background suppression by frame subtraction are shown. On- board processed Fourier spectra and Fourier power spectra of selected frame lines are shown. Curve-fitted representations are compared for clear air, cloud and land clutter, and a commercial aircraft at close range.
