Design and implementation method of a multifunctional test and analysis sound simulator

Abstract

The present invention proposes a design and implementation method of a multi-functional test and analysis sound simulator. The method includes starting a target simulation function module, a signal acquisition and analysis function module, a replay analysis module and a sound ray drawing module according to user selection. Parameter configuration and operation result display are performed through the display and control interface, and the auxiliary module is started to help the system complete the scheduled work. The data is transmitted to the transmitter box for signal transmission. A multifunctional test and analysis sound simulator designed and implemented by the present invention integrates various practical functions required for field tests of sonar equipment, has a good human-computer interaction interface, and is of great significance for improving experiment efficiency and saving experiment costs.

Description

technical field [0001] The invention relates to the technical field of multifunctional sound simulators, in particular to a design and implementation method of a multifunctional test and analysis sound simulator. Background technique [0002] The ocean environment is complex and changeable, and information transmission in ocean channels is more difficult than in air channels. Electromagnetic waves, which are excellent information transmission carriers in the atmospheric environment, due to their high-frequency characteristics and short wavelengths, propagate and attenuate rapidly in liquid media, and have limited operating distances. They are only available in some special cases such as underwater docking and other short-distance operations. However, there is only one way for long-distance information transmission to use sound waves as a carrier to carry information. Acoustic signals have good propagation characteristics in seawater media, with long propagation distances, s...
