Investigation of the Potentialities of Using Seismic Sensors for the Detection of Ships and Other Naval Platforms.

摘要

The potential of using geophones and seismic paths for the acoustic detection of ships is investigated using available data and theory. The use of seismic paths offer the potential of a reliable detection range that is independent of the sound velocity profile in the water. An estimate of the achievable reliable range using a multiaxial geophone is 10 to 20 km. The attenuation of sound in the sediment is the controlling factor in signal propagation. The estimates need to be confirmed by experimental investigation. (Author)
