TRM4 is one of the core components of ECOMOS (European Computer Model for Optronic System Performance Prediction). ECOMOS is a novel evaluation approach, which in the long run should also allow to evaluate the influence of advanced digital signal processing techniques on the performance of optronic systems.

TRM4 is a commonly used model for assessing device and range performance of electro-optical imagers. The latest version, TRM4.v2, has been released by Fraunhofer IOSB of Germany in June 2016. While its predecessor, TRM3, was developed for thermal imagers, assuming blackbody targets and backgrounds, TRM4 extends the TRM approach to assess three imager categories: imagers that exploit emitted ...

The aim of the range performance model TRM4 is the evaluation of imager performances considering the entire electro-optical imaging chain, including the resulting image's observation on a display. Usually, it is assumed that the image is viewed in a mostly optimized setting, where factors such as suboptimal display contrast are not a limiting factor to the overall system. However, this cannot ...

Model-based performance assessment is a valuable approach in the process of designing or comparing electrooptical and infrared imagers since it alleviates the need for expensive field measurement campaigns. TRM4 serves this purpose and is primarily used to calculate the range performance based on parameters of the imaging system and the environmental conditions. It features a validated ...

Range performance is the key figure for assessing and comparing electro-optical imagers for target acquisition. TRM4 is a widely used model to calculate the range performance based on parameters of the imaging system and the environmental conditions. It enables the user to assess imaging devices working in the spectral range from the visible to the thermal infrared using the same modeling ...
