“…However, spatial signal focusing may fail when the channel changes much within the exchange of the prob signal and cannot be considered symmetric. The most common approach for UWAC LPD is the use of direct-sequence spread-spectrum (DSSS) signaling, where signals are spread in the frequency domain and signal power spectral density is reduced while maintaining data rate or while transmitting at lower power and at reduced data rate [5]. Signal interception of DSSS signals becomes more difficult the more signals are spread, while by de-spreading the signals the receiver can operate at the lower SNPR [6].…”

The ability to avoid detection of a communication signal in the underwater acoustic channel is extremely important for underwater acoustic communication (UWAC) systems when used for military-related applications. Furthermore, low probability of detection (LPD) may reduce environmental impact of UWAC as communication signals can be transmitted at lower power. In this paper, we study the LPD capability of UWAC systems. We consider an interceptor employing energy detector and calculate the minimal signal-to-noise power ratio (SNPR) which satisfies its required performance. For the receiver, we calculate the minimal required SNPR to allow reliable detection and decoding of a data packet using spread-spectrum signaling. We then analyze the LPD capability of the system for different channel and communication parameters.Index Terms-Underwater acoustic communication, low probability of detection, direct-sequence spread-spectrum 978-1-4799-4918-2/14/$31.00 ©2014 IEEE
