Abstract
An underwater acoustic deception system deceives a sensor installed on a threat existing in or on water by acoustic effect in order to protect ships from the threat. The underwater acoustic deception system is provided with a control device, a laser oscillator and emission optical system. The control device determines a focusing position to focus a laser beam () in water in order to generate bubbles () at a desired position with a desired scale and emission parameters of the laser beam (). The laser oscillator generates the laser beam () configured to focus in water and generate bubbles. The emission optical system emits the generated laser beam () to the focusing position. The underwater acoustic deception system deceives an arbitrary sensor existing in the water by acoustic effect of the bubbles () on the surroundings.
