ABSTRACT:
An ultrasonic flaw detecting technique in which reflection echoes of ultrasonic waves transmitted from a plurality of vibrator elements are received, and a composite signal obtained by composing the reception signals is supplied to a composite signal reception processing circuit. A method and an apparatus in which the existence of the composite signal is detected at a first time point at which the composite signal based on the reflection echoes from an inspection target in a main lobe can be detected and at a second and a third time point which are in advance of and later than the first time point respectively and at which the composite signal based on the reflection echoes from an inspection target in the main lobe can not be detected, so that when the existence of the composite signal is detected only at the first time point, it is determined that the composite signal is that based on the reflection echoes from the inspection target.
