Localization of a Coherent Acoustic Source in a Shallow-Water Channel Using the Partially Calibrated Adaptive Antenna Array

Аннотация

We consider the problem of determining the location of a coherent acoustic source in a shallowwater channel using a partially calibrated antenna array. To solve this problem, we develop a reduced-rank stable projection algorithm, which is the generalization of the RARE method to the case of signal reception under the conditions of incomplete information on the propagation medium. The results of experimental validation of the proposed approach, which show its efficiency under the conditions of an actual shallow-water area, are presented.
