CONSIDERATIONS FOR OPERATIONALIZING CAPABILITIES FOR EMBEDDED COMMUNICATIONS SIGNALS IN MARITIME RADAR

In this work, we explore the feasibility of injecting data into an existing radar waveform. Specifically, we investigate how to embed communications signals within a navigation radar pulse to explore the potentials for a) receiving and demodulating the associated communications data, and b) identifying potential vulnerabilities/effects to maritime networks that inadvertently receive data in this manner. In this thesis, we advance previous work by utilizing a more practical, navigation-like radar waveform instead of an idealized, rectangular pulse previously studied. We utilize a particular radar system in order to calculate its actual throughput with the use of an embedded or combined signal. Considering that the radar waveform may not be detected at times due to modest radar-to-communications power ratio, we calculate the embedded communications’ effective symbol error ratio. We also demonstrate the spectrum of the radar-embedded communications waveform on a carrier via signal generator and spectrum analyzer.http://archive.org/details/considerationsfo1094561390Lieutenant Commander, United States NavyApproved for public release; distribution is unlimited
