Abstract
This paper details the development of a modularized system level model of a sensor whose detector dimensions may be small with respect to the distance between adjacent detectors. The effects of individual system components and characteristics such as target to background properties, collection optics, detectors, and classifiers will be modeled. These individual effects will then be combined to provide an overall system performance model. The model will facilitate design trade offs for Unattended Ground Sensors. The size and power restrictions of these sensors often preclude these sensors from being effective in high resolution applications such as target identification. Consequently, existing imager performance models are not directly applicable. However, these systems are well suited for applications such as broad scale classifications or differentiations between targets such as humans, animals or small vehicles. Furthermore, these sensors do not have to be spaced closely together to be effective in these applications. Therefore, the demand for these sensors is increasing for both the military and homeland security.
