Abstract
The SWAMI suite of programs in use at DRDC Atlantic enables a user to produce modelled reverberation time series data based on a series of input parameters that describe the acoustic parameters of an area of a seabed. The modelled data can be compared to recorded reverberation data and a quantitative measurement can be made that essentially tests the goodness of fit of the modelled data to the measured values. A contract was issued to design a program that would iteratively vary the values of the geoacoustic parameters input to the SWAMI programs and then run them, each time comparing the model results to a set of measured data. In this manner the program would arrive at a set of values that would produce model results that were as close to the measured data as SWAMI could provide.
