Abstract
Tools, systems, and methods may be configured for or include detecting one or more underground acoustic sources and localizing them in depth and radial distance from a wellbore using an array of at least three acoustic sensors disposed in the wellbore in conjunction with array-signal-processing that accounts for movement of the acoustic sensors and spatial aliasing by using adaptive time dependent modelled steering vector weights.
