Obtaining a License for TRM4

This page explains how to request a license for the TRM4 software and summarizes the main restrictions defined in the license agreement.

About TRM4

TRM4 is software for performance modeling of electro-optical and infrared imaging systems. Its development is funded by the German government. The calculation results are based on the analytical TRM4 model, which provides a method for comparing the performance of electro-optical and infrared imaging systems in different military applications. Further information about the model and references to validation studies are available on the “Range performance model TRM4” web page.

As with any analytical model, TRM4 represents a simplified description of real-world conditions, including the target, scenery, atmosphere, imaging system, and human perception processes. Consequently, results generated by the software may differ from results observed in field tests or human observer experiments.

License restrictions

Use of TRM4 is subject to the terms of the license agreement. In particular:

The licensee is the end user of the software. Therefore, making the software available to others is prohibited.

The use of the software is territorially limited to full member states of NATO and/or EU, as well as Switzerland.

The use of TRM4 is limited to the licensee’s internal purposes, which excludes provision of services or consultation to third parties.
