Abstract
An apparatus and method for detecting utilities buried in the ground wherein an array of sonic receivers are arranged in rows and ranks against the ground and a corresponding array of sonic transmitters are arranged relative to the array of sonic receivers so that a distance between each sonic transmitter and each adjacent sonic receiver is the same. Echoes generated by the apparatus may then be normalized, averaged and compared to the original echoes to develop a profile of the buried utility.
