Near-Field Leak Localization Method Based On Linear array

This study addresses leakage sources in plate structures by proposing a method for near-field and far-field recognition and full-field localization based on a linear piezoelectric sensor array. The method receives leakage signals through sensors, autonomously sets thresholds, and classifies the leakage source as near-field or far-field according to the sub-array localization results. By combining an improved two-dimensional MUSIC algorithm, high-precision localization is achieved, ultimately realizing near-field localization of leakage sources in plate structures.
