- Abstract
- In this paper an efficacy measure for signal detectors is considered. This measure doesn't take into account only the usual values of detection probability gamma and false alarm probability alpha but also the time between suceeding decisions. First a general detector is described with the characteristics of time which contributes to its decisions. With this general detector the decision mechanism of any detector can be described. The calculation of this efficacy measure is based on the meantime between alarms, which is a function of the detection probability, the false alarm probability and the time between succeeding decisions. The meantime between detections and the meantime between the false alarms is calculated as a function of the meantime between alarms. These are the important parameters which determine the efficacy measure.
