This paper proposes an underwater sound localization technique aiming at accurate localization of the wreck at sea in the aftermath of an aircraft accident. This technique is based on the combination of chaoticelectronic signal and sensor array. It uses as the spread spectrum code the optimized Logistic sequence and finds the range using the auto-correlation characteristics of good chaotic spread spectrum. At the receiving end, electronic signal as received by the sensor array is processed using minimum variance distortion-less response (MVDR) self-adaptive beam forming algorithm. In the process of direction finding, this technique suppresses satisfactorily the noises coming from directions other than electronic signal source. This system was put to an experimental verification in which it was placed at a location 500 m off the sound source. This test gave an error of range finding below 0.40% and an error of incoming wave direction finding below 1.67%, suggesting that this technique is of some practical engineering value in the field of underwater acoustic communication.
