Abstract
This thesis describes the development and demonstrates the use of SUBTRAN, a submarine transient detection computer simulation model. SUBTRAN provides, at the microcomputer level, a framework that can be used to investigate how transient detection and false transient detection opportunities affect the expected time to steady-state (continuous) detection. Monte Carlo methods are employed to simulate a submarine versus submarine passive acoustic detection search scenario. The scenario terminates when steady-state detection occurs. Detection is modeled using a signal excess threshold crossing model. Random fluctuations in the acoustic signal excess are modeled using a Lambda-Sigma Jump process. Both submarines are assumed to have a fixed speed and are constrained within a defined search area. The "target" submarine is assumed to be unable to counter-detect the "searching" submarine. Transient signals and false transient signals are determined by independent Poisson processes. Summary statistics for the times to detection are provided as output of the simulation.
