Measure of Effectiveness Analysis of Passive SONAR System for Detection [PDF]
Journal of the Korea Institute of Military Science and Technology, 2012 The optimal use of sonar systems for detection is a practical problem in a given ocean environment. In order to quantify the mission achievability in general, measure of effectiveness(MOE) is defined for specific missions. In this paper, using the specific MOE for detection, which is represented as cumulative detection probability(CDP), an integrated ...
