A Tutorial on Imaging

Abstract

Obtaining the coordinates of a military target in a weapons system computer, making an aerial photograph, mapping the terrain with side-looking radar, obtaining data for a terrain avoidance guidance system are all practical examples of imaging systems that use electromagnetic radiation. From the view point of the mathematical models we use to understand and compare such systems, they differ in detail but not in purpose. This report discusses various kinds of electromagnetic imaging systems of military interest, stressing their similarities and differences. This information should be useful to administrators who review and judge research proposals for developing military systems that use imaging devices of various kinds. Keywords: Holography, Coherent imaging, Incoherent imaging, Partially coherent imaging.
