Abstract

This paper investigates changes in target detectability due to alterations in target and clutter contrast structures brought about by sensor aliasing. A human observer model which is sensitive to structural contrast differences has been developed and is used to assess target detectability in aliased imagery generated by the TACOM Thermal Image Model. Results indicate that aliasing can influence target detectability.
