Abstract:

Despite the ubiquity of networked and radio frequency-emitting devices in the maritime domain, a robust understanding of the maritime cyber environment has not yet been fully developed. One particular area of interest within this larger environment is that of co-channelinterference between radar and communications systems. The effects of a relatively low-power in-band communications interferer ona high-power radar are investigated. Software simulation is used to determine the probability of detection and power spectral density of the combined radar-communications signal for a pulsed radar. Additionally, the impact of an interfering communications signalon the range-Doppler map of a pulse Doppler radar is investigated. The perspective of a radar operator in a maritime environment is also considered. In all cases, the communications signal is parameterized by the radar-to-communications power ratio RCR and thesymbol-rate-to-bandwidth ratio SRBR. Finally, software simulation is validated for the probability of detection case by implementing the radar detector on a field-programmable gate array FPGA similar to what would be used in a radar receiver. In all cases, embedded communications are found to have relatively little effect on radar performance.
