Abstract : A range resolving ground line sensor having the capability to determine range along the length of a pressure sensitive type line or cable by providing a time limited pulse of bias voltage which propagates down and back along the line and therefore provides a time history of the impedance changes as a function of distance (time) along the line is described.
