To explore and quantify the performance of data features for classifying the state of the scale layer of the homogeneous electrode by ultrasonic detection, this paper proposes a data robustness test method. The method takes the ultrasonic detection signal of homogeneous electrode as the research object, firstly obtains the frequency band of the reflection signal of homogeneous electrode in the ultrasonic signal with the appetite signal for the characterisation, and proposes the confidence ellipsoid robustness test of the scale layer, and proves the reasonableness of the data feature extraction in the article, which provides a certain value of engineering for the field of ultrasonic detection.
