Passive harmonic source ranging in waveguides by using mode filter. (English) Zbl 0574.76086
In this paper a new method of passive source ranging in a layered waveguide is proposed. The mode filtering processor was used to process the field data of a vertical array to obtain individual modes. The source range information can be extracted by measurement of three individual mode phases.
