  • Object-oriented system for simulating sonar target acoustic scattering
    Patent number: 6584300
    Abstract: A detailed sonar target scattering simulation system using object-oriented techniques to implement a broadband computational simulation of a plurality of detailed target highlight features. The class library includes a target class and a highlight base class from which a plurality of highlight subclasses are drawn to accurately represent a wide range of target highlight features. The resulting standard high-level framework allows many operations to be naturally defined and used with reduced software code errors, thereby improving computational effectiveness. The system includes a data processor, a user interface for accepting user commands and data, a display for displaying the simulated acoustic received signal, and a data memory for storing information representing the properties of the acoustic source signal and the positions of the acoustic source signal, the acoustic received signal and the target, and a class library including a target class, a highlight base class and one or more highlight subclasses.
