<p>The models for determing convergence zone Gain (G) were developed using a linearized
Sound Speed Profile (SSP) and applying ray tracing theory. The SSP was divided into
three cases; bilinear, bilinear with isospeed layer, and bilinear with mixed layer.
Two analytical solutions were developed using Taylor series and binomial series
expansions to determine G, one for the bilinear and bilinear with isospeed layer, and
the other for the bilinear with a mixed layer. The solutions for G are exclusively a
function of the SSP gradients. Each solution was compared to the solutions from ray
tracing and the solutions from the Integrated Carrier ASW Prediction System (ICAPS)
(which runs on mainframe computers and requires more data in addition to the SSP).
When the SSP'S were not too unusual, the solutions for G were fairly close when compared
to ray tracing and ICAPS.
