Paper Abstract
Currently there is no model validation to confirm the extension of the US Army Night Vision and Electronic Sensors
Directorate (NVESD) field-of-view (FOV) urban search model to a field-of-regard (FOR) model. Human perception
testing has been performed at NVESD to further understand the search and target acquisition task within a defined FOR
in the urban environment. A modification to the current search model is proposed based on 30 simulated long-wave
infrared (LWIR) FORs created by the NVESD Electro-optics Simulation Tool-kit. The FOR model was tested against
human observer performance using an additional set of real LWIR FOR images that were captured at a US Army
MOUT training site. The real imagery included thermal signatures during both day and night, and visible imagery
during the day. Comparisons have been made between these perception test results and the time-limited search model.
Current model assumptions concerning the relationship between the FOV search and FOR search tasks are evaluated
and discussed.
