Abstract

In order to detect leakage and deformation of drainpipe inner-wall, ultrasound multi-beam sonar detecting method is applied on the drainpipe detecting. Mills decussating sensor array and phase rotation scanning are used to scan the inner-wall of the drainpipe in 2 dimensions. Methods based on the gradient method and wavelet transform data processing are proposed and a good 3-D acoustic imaging is get. The experiments verified phased theory and the wavelet transform sonar imaging algorithm in the correctness and validity.Then drainpipe detecting sonar imaging system is designed.
