Parameter Optimization of High Pressure Water-Jet Target Detection

Abstract:

In order to detect and locate the water-jet target by the reflected sound signal generated while high pressure water-jet impacted the target, a variety of relevant parameters should be optimized to make microphone acquiring the effective reflected sound signal. The basic principle of high pressure water-jet target detection theory and the parameters needed set were introduced. The experimental device was set up to acquire the reflected sound signal. The wavelet denoising and signal decomposition software was programmed by using MATLAB. The communication between LabVIEW and MATLAB was realized by calling the Math script node which processes the reflected sound signal denoising and decomposition. The optimal parameters are selected based on the voltage amplitude level and stability of the reflected sound signal eigenvalues on the mutation point which is produced on the edges of the target.
