Estimating the detection capabilities of permanently installed sensors
J Corcoran
The structural integrity assurance provided by a permanently installed sensor is determined by its detection capability; the probability of detecting candidate defects must therefore be quantitatively assessed. Assessing the detection capability of permanently installed sensors is challenging due to the fixed sensor location and uncertainty in where damage may initiate. A framework is proposed that takes into account the spatial probability of where damage may initiate and the spatial distribution of sensor sensitivity. Illustrative examples are provided that contrast the performance of high-sensitivity, low-area-coverage sensors to low-sensitivity, high-area-coverage sensors in different situations.
