ABSTRACT:
An ultrasonic non-destructive inspecting apparatus is constructed to comprise a transmission signal generator, an ultrasonic probe, a correlator and an adder wherein a transmission signal based on a sequence is generated and transmitted to a specimen, its echo is correlation processed with an appropriate reference signal, and the results of the correlation processes are summed to judge a reflection matter within the specimen.
