Abstract

Beam-Forming is a mature source location algorithm which is already used in health detection of large concrete structures. However, this method is mostly used to positive detection or detection and location of sudden signal. Beam-forming arithmetic will be used to passively detect and locate the continuous leakage signal, utilizing an L-shape sensor array to gather the leakage signal. By carrying out experiments on a 1m×1m×2.5mm size magnalium plate, the influence of distance between transducer array and the signal source on the accuracy of source location of continuous leakage signal will be studied both on theory and experiment. The experimental result will be a reference for distribution of sensor array when this method is used in practical application.
