A Two-level Distributed Interactive Simulation Architecture for Radar Frequency Assignment

This paper presents a two-level architecture for the implementation of a distributed simulation environment for interference detection and frequency assignment in naval radar units. The Java-based simulation is designed as a two level architecture incorporating i) multiple radars on each ship controlled through a lower-level intra-ship interference control module and, ii) multiple ships in a group coordinated through a higher-level interference control module. Each ship’s interference detection and control mechanism is composed of these two separate levels, called a control agent, dynamically coordinating with one another in eliminating interference problems. In addition, the control agent is a multi-threaded architecture that incorporates the maintenance of a distributed data base system, that contains periodically updated radar information.
