(author), Lam, F.P.A. (author), Newhall, A.E. (author), Lin, Y.T. (author), Lynch, J.F. (author)During naval operations, sonar performance estimates often need to be computed in-situ with limited environmental information. This calls for the use of fast acoustic propagation models. Many naval operations are carried out in challenging and dynamic environments. This makes acoustic propagation and sonar performance behavior particularly...conference paper 2013

Lam, F.P.A. (author), TNO Defensie en Veiligheid (author)Naval operations in coastal waters are a huge challenge for modelling support in several disciplines. For example, any decision dependent on sonar performance could be depending on a proper translation of input from a reliable oceanographic model, that relies itself on reliable input from a meteorological model. Obvious to mention that many...conference paper 2006

(author), TNO Fysisch en Elektronisch Laboratorium (author)In this paper a description is given of a physically based theoretical ocean backscatter model (called the VIERS-1 model) for intermediate incidence angles, and a comparison of its performance against the CMOD4 empirical model is made. The VIERS-1 scatterometer algorithm is based on a two-scale composite surface model which includes both...article 1998
