Description: The report contains an analysis of an active sonar detection model. A k-out-of-n positive      signal excess criterion determines echo detection. The analysis is based on encounter      simulations in which signal excess fluctuations are described by either a Gauss-Markov      process or a lambda-sigma jump process. For both processes, encounter probability      estimates generated by the simulations suggest that the probability of detection during an      encounter is maximum when the relaxation time for the process is in the neighborhood of the      time required to generate k consecutive pings given the time between pings remains constant.      Keywords: Active sonar detection models; Signal excess fluctuation models. (RH)
