Abstract
Potentialities of the pulsed acoustic forward-scattering location with the use of time separation of the intense direct and weak scattered signals propagating at a small angle to one another are considered. Two types of interference are taken into account: nonstationary observation conditions under the effect of currents, which affect the arrival times of the direct and scattered signals, and nonstationary reverberation. It is shown that, in the presence of these interferences, the application of the correlation transformation equivalent to the time reversal of waves has an advantage over the conventional location technique based on the determination of the signal travel times.
