摘要： An ultrasonic detection device is constructed in such a way as to include a discriminating processing unit (a time width detecting part 13 and a pulse width discrimination part 14) for approximating the shape of each signal which is a reflection signal which is reflected from an object as a result of transmitting a ultrasonic pulse toward the object, or a noise as an isosceles triangle and computing a pulse time width equal to the length of the base of the approximating isosceles triangle, and for discriminating between the reflection signal and the noise signal by determining whether the computed pulse time width exceeds a predetermined pulse width discrimination threshold. Therefore, the ultrasonic detection device can determine the pulse time width with stability, and carry out the discriminating process with a high degree of reliability.
