A simple deconvolution method for NAPOLI'85
An inverse filter (deconvolution in the frequency domain) is appliedto acoustic results from the NAPOLI '85 experiment in order to obtain an estimate of the impulse response function of the medium. This method represents a very simple approach and requires few assumptions, making it robust to conceptual errors. Signals were generated by small explosive charges and received at two hydrophonearrays placed at 500 m and 5000 m range from the source. To provide the impulse response function of the medium signals of the two hydrophone arrays were used in a deconvolution algorithm. The algorithm is described in detail and some measurement results are shown.
