AUTOMATIC BASE GATE POSITIONING CIRCUIT
An automatic base gate positioning circuit for use in rail flaw detection is disclosed which includes the generation of a string of uniformly spaced pulses corresponding to known rail depth, correlating said pulses with sonic echoes, averaging and storing the correlated signals, and developing a signal representing the rail depth for comparison with an echo from the rail base.
