NUWC Shallow Water Curtain Effect with Biot Bottom Loss: System Impact

Abstract

The Curtain Effect was originally conceived to compare the relative rates of loss of spreading and attenuation in deep water in order to estimate possible attainable acoustic detection ranges. It was later modified to compare spreading, attenuation, and bottom loss in shallow water for the same purpose (NUWC-NL Technical Document 4009, 2 March 1992). We now compare the Shallow Water Curtain under strongly downward refracting conditions for various source/ receiver depths assuming an angular dependent Biot bottom loss. The result is a diagram which allows the visualization of the relative trade-off between source depth and frequency under these conditions.
