Title:Maritime Surveillance Sensing Using Underwater High Frequency Acoustic Communication Receivers
Abstract:High-frequency acoustic modems are required to provide undersea communication networks to support covert surveillance operations. These modems can also be used as platforms for compact, low power surveillance sensors and processing. A natural first step would be to integrate a capability for passive acoustic detection of ships and submarines. A multi-phase effort is proposed for integrating passive acoustic detection, feature extraction, and automated classification into existing undersea modems being developed by SOCOM. A team-based approach will be used to provide the wide range of capabilities required for this effort. Extensive reuse will be made of existing development efforts at Teledyne-Benthos, Analysis, Design & Diagnostics (AD&D), and Advanced Acoustic Concepts (AAC) to minimize the development risk. The Teledyne-Benthos SM 75 undersea modem will be used as a target platform, providing an undersea networking capability while allowing the team to define the changes required to support an automated passive acoustic detection capability. AD&D will provide expertise in acoustic data collection, data analysis, and passive classification of narrowband, modulated and unmodulated broadband, acoustic intercept, and transient signals. AAC will modify existing CAUSS (Common Airborne USW Sensor Software) sonobuoy processing software to provide passive acoustic detection, feature extraction, and message generation and compression capabilities.

Title:Maritime Surveillance Using Underwater Communication Receivers
Abstract:Many SOCOM-specific, passive, maritime, acoustic-surveillance operations cannot be accomplished using conventional sonar-system technologies. Maritime, passive-acoustic surveillance using some combination of submarines and the Advanced Deployable System is a traditional surveillance mission. But, the deployment and use of these capital-intensive assets for surveillance of many shallow-water passages, ports, and harbors open to use by irregular adversaries is inappropriate. These traditional technologies are also focused on long-range and large-area detection using sensors and signal processing that does not include non-traditional targets such as small surface craft. Our proposal addresses the design, construction and testing of sensors and signal-processing software for unconventional maritime surveillance. The sensors are variants of proven underwater-modem technology. In Phase I, signal-processing software appropriate to the constraints of this sensor and mission will be constructed and tested using data from the Harsh Environments Program.

Title:Maritime Surveillance Sensing Using Underwater High Frequency Acoustic Communication Receivers
Abstract:The Navy, the academic oceanographic community and the oil industry have embraced the use of underwater acoustic modems to take advantage of the many benefits that wireless operation brings to their applications. In this proposed SBIR effort, HLS Research Inc will take advantage of the resources already present in an acoustic modem, namely the acoustic pressure sensors and the signal processing capability, to develop detection, classification and localization/tracking algorithms for exploiting passively sensed acoustic data when the communications functions are not being used. The goal is to provide acoustic situational awareness of transiting surface ships and undersea platforms, using their acoustic signatures. HLS Research has organized or participated in a variety of high-frequency at-sea experiments, focused on both acoustic communications and marine mammal studies (where the passage of surface and other ships was of course an interference), in which high-frequency raw time series was recorded for days or weeks at a time, often on arrays of hydrophones. HLS Research will also take advantage of additional data-collection opportunities as they arise. These datasets will provide realistic data for a convincing demonstration of feasibility in this Phase I effort.

Title:Maritime Surveillance Sensing Using Underwater High Frequency Acoustic Communication Receivers
Abstract:Special Operations Command desires an innovative approach to augment underwater acoustic modems with a passive sensing capability to detect ships and submarines. While providing the existing communications function, it is feasible to take advantage of the existing infrastructure by tapping the digital data stream from the acoustic modem receiver front end, and apply additional detection and classification signal processing to provide this additional ship detection function. This could expand the role of acoustic modems from being communication nodes in the underwater information grid to having both sensing and communication capabilities. The Progeny Systems Corporation team will conduct the necessary engineering analysis to demonstrate the feasibility of automated detection and classification of shipping using a commercial acoustic modem as the sensing element. In our Phase I effort we intend to obtain relevant target and ambient signatures in commercial acoustic modem high frequency (HF) detection bands, develop detection algorithms through application of Acoustic Intercept and Ranging (AI&R) processing strings to the target signature and noise data sets, assess the suitability of applying submarine sonar classification algorithms to the detected signatures, and derive system requirements and develop the conceptual hardware and software design for the Phase II prototype.
