Mitigation methods and techniques for enhancing sonar operational confidence / Mark Gammon, Chris Strode and Marcel Lefrançois. : D69-40/2016E-PDF

"There are numerous challenges to effectively model sonar performance given the variability in the ocean acoustic parameters, and the uncertainties with respect to factors such as the target strength. As such, in most cases it is well recognized by the operational community that it is nearly impossible to accurately predict the performance of a sonar system for the full range of operational settings. Given this situation, numerousinitiatives both technical and operational are required to harmoniously provide a level ofconfidence in sonar prediction under practical conditions. Some initiatives and tools thatare being utilized include the NATO Multi-Static Tactical Planning Aid (MSTPA) and the Environmental Modelling Manager (EMM). The latter is embedded in a developmental version of the Canadian Maritime Acoustic Processing System (MAPS). These are presented with the caveat that some may have a greater or lesser impact on operator confidence under realistic operational conditions"--Abstract, p. 573.
