Paper Abstract

In the urban operations (UO) environment, it may be necessary to identify various vehicles that can be referred to as non-traditional vehicles. A police vehicle might require a different response than a civilian vehicle, or a tactical vehicle. This research reports the measured 50% probability of identification cycle criteria (N50s and V50s) required to identify a different vehicle set than previously researched at NVESD. Longwave infrared (LWIR) and midwave infrared (MWIR) imagery of twelve vehicles at twelve different aspects was collected. Some of the vehicles in this confusion set include an ambulance, a police sedan, a HMMWV, and a pickup truck. This set of vehicles represents those commonly found in urban environments. The images were blurred to reduce the number of resolvable cycles. The results of the human perception experiments allowed the 50% probability of identification cycle criteria (N50s and V50s) to be measured. These results will allow the modeling of sensor performance in the urban terrain for infrared imagers.
