  • Abstract: As an acoustic communications medium, water is characterized by frequency dependent attenuation, short range, very low bandwidth, scattering, and multi-path. It is generally difficult to acoustically communicate even terse messages underwater much less images. For the naval mine counter-measures mission, there is value for transmitting images, if possible. The contribution of this paper is a methodology to encode, compress and transmit small (100s of kB) side-scan sonar images underwater with micromodems. The work has been validated through several at-sea trials. The reconstruction of the received images is of a fidelity that operators can visually recognize targets they normally look for in these images.
