Abstract

This document describes the work of the project Dynamic Electronic Warfare Duel Simulation during 2009. The project uses and improves the multispectral framework EWSim (Electronic Warfare Simulation interface model) for distributed electronic warfare simulations. The framework consists of three parts, one for scenario planning and configuration, where models are configured and where some range calculations can be made, one for dynamic duels, and finally one assessment module where the duels can be replayed and logged data can be analyzed. EWSim contains models of platforms, countermeasures, warners, sensors and missiles with target trackers and motion models. A model of a Blue Force Tracking System (BFT) has been developed during the year and this type of system can thus be evaluated in duel simulations. BFT systems are used to monitor positions and movements of own units. Devices determine their own position via GPS and then distribute the measured position and velocity etc. to other units. This is done to make for example a staff able to compile a status report. Initial modeling of frequency hopping emitters has been implemented in order to get the properties needed for direction finding equipment to detect, monitor, and possibly identify the type (nationality). To solve the problem of external countermeasure algorithms, EWSim has been supplemented by a dynamic plug-in system. The result is a flexible system that allows algorithms written for a real countermeasure platform to operate in an electronic warfare scenario in EWSim. During the year, design work has been carried out in preparation for the deployment of a radar missile with control via internal target acquisition. In the international collaboration project, EW COMARMS, we have made comparisons between this project's ESM model, Electronic Support Measures, and ISDEFE´s model. While discussing and comparing models, it has become clear that the existing radar warning model in the EWSim framework should be complemented by a more complete ESM system with classification capabilities and action proposals so that it can handle several targets in a more realistic way. For the armed forces there are guidelines for geodetic reference systems and methods for positioning that say that NATO standard STANAG 2211 (WGS84) should be used. For this reason, EWSim was further developed so that existing calculations and algorithms operate regardless of whether the scenario is an older variant of terrain, expressed in RT90, or with a new terrain in WGS84. The models included in the EWSim framework can be used in configurable scenarios from the FM´s strategic typical situation, which can be broken down into a number of typical cases, where the consequences of for instance BFT can be studied and analyzed. In these scenarios, you can then see what happens for instance if the enemy´s intelligence constantly monitors the position updates and our BFT system instead becomes a Red Force Tracking System.
