    Abstract
    The main goal of project RUMBLE has been to enhance our capability to predict active sonar detection ranges in shallow water. The idea is to measure ‘through-the-sensor’ the seabed characteristics that affects long-range acoustic propagation in shallow water. The work has included the development of an inversion method for determining bottom parameters from reverberation received by a Low frequency Active Sonar (LFAS). Two sea trials have also been performed, in order to provide data for evaluating the performance of the method. The first sea trial took place in a relatively simple area in Vestfjorden, while for the second sea trial a more difficult area in the Norwegian Trench, west of Stavanger, was chosen. The present report presents an overall assessment of the work and provides the main conclusions.
