The present report constitutes a summary of the work performed within the project Future Electronic Warfare Duel Simulation during 2016. The project was funded by the Research and Technology program Electronic warfare. The overarching goal of the project was to develop tools and methodology for electronic warfare assessment, thereby enabling their use in development of tactics, techniques and procedures in preparation for and during future electronic warfare efforts. Methodology and tools have been demonstrated on several occasions and, in addition, implemented through participation in trials and exercises with the Swedish Armed Forces. The main activities of the project have focused on the development and use of the simulation framework EWSim. Examples of improvements to the framework are: ? Improved logging and data analysis. ? Updated management of terrain data, both w.r.t. geometry and vegetation. ? New models for antenna sweeps and dynamic coverage diagrams. ? New missile models and the ability to fire on multiple targets simultaneously. ? New and improved models for both radar and image generating seekers. ? IR-simulation for use with new terrain management. ? Thorough restructuring of source code and source code management. Future work will focus on simulation models and numerical as well as visual data analysis targeting modern sensor systems for air and sea surveillance.
