Description
［開口合成処理条件の決定］
図２を参照して、決定ステップにおいて開口合成処理条件、即ち、合成幅と遅延時間を決定する際の信号処理装置１９の動作について説明する。加えて、決定ステップにおいて、遅延時間の決定に用いる、超音波信号の伝搬経路を算出する方法の例について説明する。ここで、伝搬経路とは、検査体中における超音波信号の伝搬経路である。必要に応じて、検査体中と媒体中とにおける超音波信号の伝搬経路としてもよい。また、以下では、合成幅の決定に用いる、基準位置における欠陥信号の受信音圧に対する欠陥信号の受信音圧の比である受信音圧比を算出する方法の例についても説明する。
[Determination of aperture synthesis processing conditions]
With reference to FIG. 2, the operation of the signal processing device 19 when determining the aperture synthesis processing conditions, that is, the synthesis width and the delay time in the determination step will be described. In addition, at decision step, it used to determine the delay time, an example of a method of calculating the propagation path of the ultrasonic signals. Here, the propagation path is a propagation path of the ultrasonic signal in the inspection object. As needed, it is good also as a propagation path of the ultrasonic signal in a test body and a medium. In the following, used to determine the synthesis width, also describes an example of a method for calculating a reception sound pressure ratio is the ratio of the received sound pressure of the defect signal to the received sound pressure of the defect signal at the reference position.
