Estimation of the underwater explosion depth from the modified cepstral analysis of sea reverberation

A mathematical model of the signal produced by an underwater explosion is used to obtain the dependence of the explosion depth on the argument T_k at which the cepstrum of the signal reaches its maximum. The algorithm evaluating the parameter T_k on the basis of the cepstral analysis of reverberation is substantiated. The proposed method of estimating the explosion depth is tested by experimental data to demonstrate its high accuracy.
