ABSTRACT:
To determine the speed of propagation of a signal in a medium, wave amplitude is measured over time at one or more detectors disposed within the medium so as to detect and identify signals transmitted at one or more sources disposed within said region. Frequency domain matched field processing power is calculated by matching measured with perturbation normal mode model fields, and beta coefficients which determine sound speed profiles are calculated by beta backpropagation so as to maximize the matched field processing power.
