LONG-TERM GOALS There is a critical need for reliably and rapidly detecting, identifying, and tracking submerged low observable targets in port environments, which would allow for rapid and effective neutralization of low observable threats. Without this capability, personnel, naval platforms and targets of opportunity are exposed to a cheap kill by an opportunistic threat. The long term goal of this effort is to exploit for the first time detailed active and passive signature information of

... bor threats together with advanced Bayesian classifier techniques. Ultimately it is the intent of this effort to leverage the highly successful science and technology carried out in broadband mine identification [1] and EOY reports for Award Numbers: N0001406WX20052 and N0001406WX20679]. OBJECTIVES The objective is to exploit passive and active acoustic signal information associated with submerged threats in harbors and ports in order to monitor their presence in real time. There is no known capability for reliably detecting, identifying, and tracking low observable targets in such environments, particularly at ranges ~ 1km. Submerged threats include a variety of both man-made and human targets and this project emphasizes swimmer and non-swimmer threats. This project will lead to identification and demonstration through experimentation and simulation. APPROACH The acoustic work is broken into the following areas. The first involves comprehensive, highly controlled broadband, multi-aspect measurements of swimmer related acoustic signals (both passively generated and in response to active acoustic insonification). The second area involves the development of suitable signal processing techniques including both tracking and identification Report Documentation Page Form Approved OMB No. 0704-0188 Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to Washington Headquarters Services, Directorate for Information Operations and Reports, 1215 Jefferson Davis Highway, Suite 1204, Arlington VA 22202-4302. Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to a penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number.
