Abstract : A simulation process evolved for evaluating the performance of HF-VHF multi-radio set configuration in a tactical command vehicle is discussed. Algorithms and performance models used in the simulation process are briefly described. Simulation process is for a specific application in a defined area of deployment under known operating situations. Performance simulation also includes an interference simulation model corresponding to the system model so that a real world situation is analysed to the practicable extent. Wherever statistical data or manufacturer's design data is not available, suitable default values are assumed for applicable, battlefield scenario quoted in the literature. This simulation tool can be extended to many applications (with modification to RF power of transmitters, receiver sensitivity, frequency separation, distance separation, channel spacing, frequency range, communication range, etc. of tactical vehicles operating in combinations of HF-VHF-UHF regions). |
