Abstract

The invention discloses a real-time self-measurement and evaluation method for underwater radiation noise of an underwater vehicle, and belongs to the technical field of noise monitoring and evaluation of underwater vehicles, and the method comprises the steps: enabling the underwater vehicle to keep a stable relative position relation with a towed line array in a period of time through employing a specific maneuvering mode when the underwater vehicle is in a state of towed sonar; measurement of the self-radiation noise level and characteristics is completed through formation estimation, focused beam forming and other methods, and finally, the underwater vehicle can know the self-radiation noise condition without being limited by regions and time in the navigation state and master the current sound stealth situation. The method can be used as a supplementary and reference means for evaluating the radiation noise of the underwater vehicle during navigation.
