Abstract
The cumulative probability of detection is evaluated as a metric for assessing the detectability of underwater sources that radiate transient sounds. A simple formula is presented for calculating the metric for the case of transients that are radiated at random intervals. The formula is applied to examples in which the source transits past a moving sonar platform. Maximum detectability occurs when source and sonar platform are on the same course, and vice versa. It is shown that the cumulative probability of detection assesses the effects of both the duration of source exposure and the average rate of transient occurrence.
