Thermal images of a ship target were recorded with an AGA Thermovision 780 thermal imaging system on 6-13 May 1987. These images were used to produce temperature distributions of the ship. The temperatures predicted with thermistors at eight locations on the ships superstructure. An empirical modification based on the identity of the ambient and local atmospheric conditions was developed for the atmospheric compensation algorithm. The predicted temperatures were found to agree with the actual temperatures within 1.5 C in 77 percent of the measurements. The Contrast Transfer Function CTF, Modulation Transfer Function MTF, and Minimum Resolvable Temperature Difference MRTD were determined for the Thermovision using flat black painted aluminum bar targets. The resultant curves showed the expected form with some experimental scatter at higher spatial frequencies.
