Longitudinal scale sound field simulation system of ship

Abstract

The invention discloses a longitudinal scale sound field simulation system of a ship. A longitudinal scale sound field characteristic of a ship is added on the basis of a traditional ship simulation,a scale of a simulated ship can be adjusted, and ships withthedifferent longitudinal scale sound field characteristic can be simulated. According to the longitudinal scale sound field simulation system of the ship, a point sound source located in the tail part of a casing is distributed and recycled through a retracting system, so that length of the point sound source laid out along the length direction of the ship changes, thus sound fields of the ships with the different longitudinal length characteristics can be simulated, operation is convenient, and using is flexible; and an active acoustic fuze signal can be received and reconstructed by adopting an active acoustic simulation segment, a reconstructed signal is emitted through an independent emitting unit, and emission intensity is controllable, and simulationof different ship target strengths and different ship speeds can be realized.

Description

technical field [0001] The invention relates to the field of non-contact mine-sweeping, in particular to a ship longitudinal scale sound field simulation system. Background technique [0002] The improvement of industrial technology has promoted the further development of mine fuze technology, the analysis of ship sound field characteristics has become more and more in-depth, and new mine fuze anti-sweep technologies have been proposed continuously. The mine fuze judges the ship target by receiving and identifying the longitudinal scale sound field. At the same time, the active acoustic fuze is used for the final confirmation of the target, which requires the acoustic mine-sweeping device to be more complex and large, which greatly increases the difficulty of mine-sweeping operations. [0003] The current international mainstream ship sound field simulation equipment is still based on ship sound field intensity, frequency spectrum and other characteristics. It is easy to be ...

Problems solved by technology

The mine fuze judges the ship target by receiving and identifying the longitudinal scale sound field, and at the same time uses the active acoustic fuze for final confirmation of the target, which requires the acoustic mine sweeping device to be more complex and large, which greatly increases the difficulty of mine sweeping operations

[0003] The current international mainstream ship sound field simulation equipment is still based on ship sound field intensity, spectrum and other characteristics for simulation, it is easy to be recognized by new mines and resist sweeping, and it does not have active sound simulation capabilities, and cannot deal with active sound fuzes of mines
