Title: Low Probability of Recognition Constraint Covert Underwater Acoustic Communication
Abstract:
Low Probability of Recognition constraint communication is a hot research area where the intruder has less chance to recognize the communication signal as a communication waveform. The communication signal is made akin to the natural sounds present in the environment and data is transmitted by slightly varying the frequency, amplitude, or time interval within the characteristic range of natural noise. The eavesdropper is tricked and recognizes the communication signal as the natural noise of the environment or channel due to signal characteristics. The covert information is encoded or watermarked at the natural sound carrier through a unique method that is known to the transmitter and receiver. The mimicked signal can be detected by the eavesdropper but it is excluded in the process of recognition and classification as it compels an intruder to assume it as the natural sound and the information is kept furtive. Excellent LPR characteristics are achieved. Further communication is performed at high SNR and transmission distance can be increased within the limits of acoustic communication.
In applications such as underwater submarine communications, frogman communications, and positioning and navigation networks, underwater acoustic communications require information to be transmitted covertly. This research focuses on biologically inspired covert underwater acoustic communication mimicking sea natural noise. Various techniques for stealthy communication in underwater acoustic channels have been analyzed and compared. Their imperceptibility, capacity, and robustness are analyzed and future research direction is highlighted.
