Abstract

The invention provides a ship noise spectrum modulation method and device. The method comprises the following steps: receiving a noise signal collected by a noise measuring instrument disposed on a ship, the noise signal comprises noise emitted by the ship sailing in a target sea area and noise emitted by a noise jammer installed on the ship in the target sea area; obtaining spectrum data of the noise signal; and under the condition that the frequency spectrum data is not matched with the standard frequency spectrum of the environmental noise of the target sea area, adjusting the emission parameters of the noise jammer according to the standard frequency spectrum until the frequency spectrum data is matched with the standard frequency spectrum.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a ship noise spectrum modulation method and device. Background technique [0002] The concealment of the ship is the key. Therefore, controlling the noise of the ship so that it cannot be detected by the enemy's sonar and other detection equipment is the core of the ship design. At present, the noise level of ships has been effectively reduced by means of floating raft installation, pump jet propulsion, and hydrodynamic shape design. [0003] However, due to the complex marine environment in which ships sail, the requirements for operating conditions of ships tend to be diversified. Therefore, how to continue to ensure the concealment of ships to a certain extent under the requirements of diversified operating conditions in complex marine environments, especially when the noise of ships starting and switching power is difficult to reduce, is the current issue. Difficult probl...
