Modeling realistic target acquisition using infrared sensors in multiple observer scenarios Conference Paper uri icon

abstract

  • To accurately measure the effectiveness of an infrared sensor for military or industrial purposes, the interaction between the human operator and the sensor must be considered. In particular, modeling the search process is crucial towards measuring the length of time and probability of success of target acquisition in a particular scenario. The CNVEO (Center for Night Vision and Electro-Optics) search model, used by the US armed forces and several allied coutries, is essentially a single-target, single-observer model. In this paper, we extend the model to the case where several observers are searching for the target under changing atmospheric conditions. The obscurant/atmosphere is characterized by an average transmission coefficient, a spatial variance, and a persistence time during which the obscurant/atmosphere is assumed to be fairly constant. Correlation between observers is …
