UUV navigation radiation noise measurement system

The invention discloses a UUV navigation radiation noise measurement system, and belongs to the technical field of noise measurement processing. According to the system, after an aircraft is placed, the diving depth h1 is recorded, an underwater acoustic sensor is placed at the position L away from the aircraft, the depth h2 of the sensor is recorded, and the distance d between the aircraft and the acoustic sensor is calculated according to the distance. The method comprises the following steps: the vehicle sails for a certain distance along the linear direction, the distance is recorded as l, the noise of the vehicle in the sailing time is recorded, the distance between the vehicle and an underwater acoustic sensor is utilized to carry out rapid normalization processing on the measured noise, and the radiation noise source level Ls of the vehicle is obtained. By optimizing the measurement system, the problem of large noise caused by a responder in the prior art is solved, meanwhile, the problem of poor calcu
