Abstract
A method for operation of an acoustic tool, having a plurality of acoustic sensors, may include receiving acoustic waves from an acoustic source located at a depth in a borehole. A selected location (e.g., central location) of the acoustic sensor array may be positioned substantially at the depth of the acoustic source based on a symmetricity of an upper and lower section of a frequency-wavenumber (f-k) transform pattern with respect to a selected wavenumber. A radial distance from the acoustic source to the acoustic tool may be determined based on a theoretical f-k transform pattern used as a mask to filter measured data in the f-k domain.
