Abstract

Understanding the performance of wideband modulated signals under noise jamming conditions is important for advancing W/V-band military satellite communications. This research developed and validated models to predict performance degradation of a communication channel in the presence of wideband noise jamming. Channel models were developed that included both modulated communication signals and jammer signals. Integrated models included environmental link factors and practical implementation factors. Integrated models were verified and validated using outdoor radio frequency environments utilizing two W/V-band transceivers, a portable W-band jammer, and software defined radios. Experimental results demonstrated excellent agreement with integrated model predictions. Channel degradation due to the jamming as measured by the link’s bit-error-rate as a function of energy per bit to noise power was typically within 1-2 dB of model predictions for various modulation schemes and data rates. In general, the results of this research demonstrated the resilience to uplink jamming attacks afforded by wide bandwidth, narrow beamwidth W/V-band satellite communication links relative to lower frequency and lower bandwidth communication systems. This work provides the foundation for future work on secure, extremely high-frequency satellite communications for contested environments.
