发明名称 A METHOD FOR IMPROVING THE PERFORMANCE ACCURACY IN DIFFERENTIAL ABSORPTION LIDAR FOR OIL AND GAS PIPELINE LEAK DETECTION AND QUANTIFICATION
摘要 <p>An improved method for determining whether a measurement point, measured using a differential absorption LIDAR (DIAL) system, represents a plume point or a non-plume point. Concentration path lengths (CPL's) for a plurality of measurement points are determined. An average non-plume CPL, formula (I) , is provided. For each measurement point, a standard deviation, CPLsd , is calculated based on first order error propagation and it is determined that the measurement point represents a non-plume point when the Hooshmand decision rule (HDR) is met. The HDR is given formula (II) where cpl is the corresponding CPL of the measurement point being tested and T is a threshold standard deviation level.</p>
