Paper Abstract

The Thermal Range Model (TRM4)1 developed by the Fraunhofer IOSB of Germany is a commonly used performance model for military target acquisition systems. There are many similarities between the U.S Army Night Vision Integrated Performance Model (NV-IPM)2 and TRM4. Almost all of the camera performance characterizations, such as signal-to-noise calculations and modulation transfer theory are identical, only the human vision model and performance metrics differ. Utilizing the new Custom Component Generator in the NV-IPM we develop a component to calculate the Average Modulation at Optimal Phase (AMOP) and Minimum Difference Signal Perceived (MDSP) calculations used in TRM4. The results will be compared with the actual TRM4 results for a variety of imaging systems. This effort demonstrates that the NV-IPM is a versatile system design tool which can easily be extended to include a variety of image quality and performance metrics.
