Abstract:

This study is undertaken to determine whether it is possible to develop a realistic computerized mathematical model for FM tactical radios operating under the influence of enemy jamming. A simplified model of the single channel communication system with interference is developed. The various parameters of this model which affect the quality of communications is then discussed. Specifically, performance data for the VRC-12 radio for various signal-to-interference ratios is introduced and a message quality indicator is developed for various received friendly and jamming signal strengths. The results of the analysis show that it is possible to develop a realistic computerized model for tactical communications in a jamming environment. Comparisons of the propagation portion of the model with actual field tests show the results to be an accurate indication of real-world conditions while the integration of actual equipment performance under co-channel interference adds a realism to the model which enhances it usefulness as a training or planning device.
