SIMULATOR OF INPUT HYDROACOUSTIC SIGNALS OF AN INTEGRATED SYSTEM FOR UNDERWATER OBSERVATION
Discusses a simulator of input signals for hydroacoustic tools of underwater observation. The algorithms for simulating noise radiation of sea objects are considered together with the algorithms for simulating direct and reflected active hydroacoustic signals. We provide the examples of calculating input signals for detection modes of hydroacoustic complexes. Software implementation of the simulator is described in C++ created in Qt Creator environment using the class diagram and use case diagram. We consider the influence of the Doppler effect. Formation of active signal spectra are considered in the mode of hydroacoustic means detection. We describe the interaction of the simulator with an external module - system of hydrological calculations – for obtaining in-formation on the hydrology of sea environment. In order to set the experiment task, display the modes of noise-detection, active sonar, and hydroacoustic means detection we describe an interface implemented in QML.
