reportActive / Technical Report | Accession Number: AD0753443 | Open PDF

Abstract:

SHADZO is a composite program which calculates the position and shape of the first surface shadow zone as a function of the source depth for a given sound speed profile. The program is small enough to be run on a shipboard mini- computer in a few minutes.
