Abstract [en]

This paper details a radio conflict analysis conducted on a shipboard militarycommunication system for command and control, with the aim of improving antennaplacement. Cosite electromagnetic interference phenomenas such as intermodulationand harmonics interference, spurious output interference and scattering aredescribed. Scattering effects is simulated using a computational tool that calculatesantenna patters using the Method of Moments on a wire grid model. Interferencelevels are calculated from radio specifications, specifying spurious output powers andvulnerability to interference.The antenna placement on board the boat are restricted by the size of the platform,free line of sight for a remote controlled weapons station and freedom of movementfor personnel on deck. These restrictions had to be taken into account during design.The analysis show that communication can be improved significantly by simplechanges in the antenna configuration, it also gives suggestions on how to reduce thenumber of antennas in line of sight of the weapons station from four to one.
