Paper Abstract

The US Army Night Vision and Electronic Sensors Directorate (NVESD) has developed the Night Vision Integrated Performance Model (NV-IPM) for conducting system trade studies and performance evaluations for EOIR imaging systems. Many programs of record carry range performance requirements that utilize the targeting task performance (TTP) metric together with system level objective measurements of an imager. The imaging system measurements of signal intensity transfer function (SITF), 3-dimensional noise (3D Noise), instantaneous field of view (IFOV), and modulation transfer function (MTF) are combined within the measured system component that can be directly implemented in NVIPM for performance and specification evaluation. IRWindows 4TM (IRWindows) is a software package produced by Santa Barbara Infrared, Inc. (SBIR) and is used for testing electro optical systems in a variety of laboratory, production, and field environments. In this correspondence, we detail how IRWindows performs the required measurements for TTP evaluation and generates a measured system component for use in NVIPM to predict range performance of an IR imaging system. Further, we demonstrate how the range performance from system measurements is in agreement between different EOIR laboratories.
