Underwater Vehicle Noise Monitoring Based on Dasp System

Noise monitoring of underwater vehicle in real time is beneficial to the improvement of underwater vehicle quietness,strengthening its acoustic stealth performance.The composition,principle and working process of the DASP System are first introduced briefly and the processing and analysis methods of noise date are elaborated.The analysis of the measured date from sea test show the DASP System has powerful date processing ability and the analysis result is high reliability,which is very helpful for underwater vehicle noise monitoring and research.
