First Digitally Processed Image from a Spaceborne Synthetic Aperture Radar, 1978
In November 1978, a team from MacDonald, Dettwiler and Associates Ltd. (MDA) became the first to use a digital processor to reconstruct an image from Seasat-A, the first civilian spaceborne synthetic aperture radar (SAR). MDA engineers subsequently developed three of the four most important SAR digital processing algorithms that replaced the optical processing methods used previously.
