摘 要：This paper presents background on the research and development that has led to the concept of the Sensor for Environmental Assessment (SEA Buoy). It begins with references to initial data gathering missions under the Harsh Environment Program (HEP) and then proceeds to describe the Air-Expendable Multi-Parameter Environmental Probe (AEMEP), the Tactical Acoustic Measurement (TAM) sonobuoy, and the TAM Decision Aid (TAMDA) programs. It outlines the achievements of those efforts and then describes the progress made and status of the SEA buoy. The characteristics, features, and capabilities of the first article test units delivered in June 2009 are discussed. This includes a summary of the in-buoy signal processing features, a discussion of the acoustic dynamic range, and a review of the present and potential future capabilities of the stores module. A brief summary of the testing to date (April 2011) is also included. A recommendation is provided to continue the development of the SEA buoy as a crucial tool in the effective use of active and passive acoustics in Air ASW.
