Estimation of Receiver Operating Characteristic Curves for Multiping Mine Detection Using Empirical Target Data
Abstract
This report develops the formalism for computing receiver operating characteristic (ROC) curves for an active sonar detector, consisting of linear receiver processing followed by a linear envelope detector. The formalism is applicable to both single-ping and multiple-ping detection. The methodology for computing the ROC curves directly incorporates measurements of target strength as a function of aspect angle to estimate the requisite signal-plus-noise probability density function (pdf) under the assumption of Gaussian background statistics. This "empirical" approach for computing the probability of detection allows ROC curve performance to be estimated for multiple ping integration and for any sensor-target scenario that is supported by the available target data.
