A Microcomputer Simulation Program to Model Transient and Steady-State Detection of an Evading Submarine by a Searching Submarine in a False Transient Environment
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 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. Keywords: SUBTRAN; Computer program; Validation; Passive detection.
