Abstract:

Convergence zone CZ prediction models are developed based on acoustic ray tracing theory as applied to linearly segmented sound velocity profiles SVP. The models were developed into three calculator programs, two for CZ range predictions under different source and receiver depth conditions and one for CZ gain and transmission loss TL predictions. The performance of the models as programmed on Hewlitt-Packard HP-67 or HP-97 programmable calculators was compared to the Fast Asymptotic Coherent Transmission FACT model which is based on similar but more elaborate theory and which is designed for use on large digital computers. Agreement of the calculator programs with the FACT model is fairly good when conditions are within the design limitations of the programs and environmental conditions are not unusual. Author
