Abstract
A method of improving damage detection in a structural health monitoring system includes obtaining a baseline set of signals corresponding to a range of values of an environmental effect variable for a plurality of first selected paths between pairs of a plurality of transducers configured in an array attached to a structure. Threshold levels are established for each of the selected paths for determining detection of damage in the structure based on differences in the baseline set of signals for the selected path. A current signal is acquired for each of the selected paths. The plurality of current signals are analyzed based on the threshold levels to detect damage in the structure.
