Advanced Underwater Technology with Emphasis on Acoustic Modeling and Systems

The Sonar Performance Prediction System (SPPS) will be introduced. The SPPS is an integrated ocean-acoustic propagation model coupled with a sonar performance prediction model. A stationary sea surveillance sonar consisting of a horizontally nested hydrophone array and a vertical transmitting/ receiving array may be used lo dctcct, localisc and track surface and subsurfacc contacts within its coveragc arca. The performance ofthe sea surveillance sonar has been investigated with the SPPS. Results ofthat performance prediction will be presented.
