A system and associated method for ranging an underwater target of interest using ambient acoustic energy from an acoustic source. The system includes a hydrophone; a correlator for correlating first and second acoustic energy originating from the acoustic source to determine a delay associated with the second acoustic energy resulting from the second acoustic energy being redirected by the target of interest; and a processor for determining a range associated with the target of interest dependently upon the delay.
