Abstract

The need for benchmarks of propagation loss, expressed eloquently by Felsen [1], was addressed in a series of propagation workshops in the 1980s. The main results of these workshops were a set of well defined propagation scenarios [2, 3] and a corresponding set of benchmark solutions [4, 5], which led in time to reliable models becoming available throughout the underwater acoustics community. Within the context of sonar performance modelling, these benchmarks provide a valuable means of testing one-way propagation models, and thereby help build confidence in passive sonar performance prediction tools.
