  • Active sonar simulation
    Patent number: 7266040
    Abstract: An exemplary embodiment of the invention relates to a method and system for displaying simulated acoustically realistic active sonar signals. The method includes simulating a realistic sounding active sonar signal that originates from a simulated sonar transmitter. The simulated sonar signal is acted upon and modified by simulated ocean effects and is received by a simulated hydrophone. The sonar signal is acoustically displayed within a simulated ocean acoustic environment that incorporates realistic sounding simulated reverberation.
