Acoustic stealth technology is one of the key technologies in the development of underwater vehicles.The performance of acoustic stealth is directly related to the operational vitality of underwater vehicles.It is very important to carry out vibration and noise reduction projects to reduce the noise radiation level of underwater vehicles.The core problem is the measurement method.As an important acoustic characteristic parameter of underwater target,the radiated acoustic power can be measured and calculated by reverberation measurement technology.The acoustic power measurement system based on reverberation technology has the advantages of accuracy,rapidity and low cost.It has the advantages of accuracy,rapidity and low cost to construct a pool acoustic characteristic measurement system for acoustic power measurement.The PC display and control software developed in this paper is the key component of the acoustic characteristic measurement system of the pool.It collects and controls the wet end of the acoustic measurement system of the pool through the dry end display and control interface.The signal processing and display output of the following experimental data based on the reverberation pool theory can realize the accurate measurement of the acoustic power pool condition radiated by the underwater target sound source,which is an important project,have important significance.Firstly,this paper introduces the principle of acoustic characteristic measurement applied in the pool measurement system,combs the radiated sound power measurement methods used in different measurement frequency bands of the pool,as the core algorithm of the software processing program of the upper computer,in which reverberation method is applied in the high frequency band,and comparison method is applied in the low frequency band.Then,according to the application characteristics of the pool measurement system,the upper computer software is designed.The software has the functions of data acquisition,data processing,real-time display,report output and function extensibility.The above functions are compiled by using LabVIEW programming software.Further,the program debugging of the upper computer software is completed to make the reverberation measurement module and the comparison measurement module run steadily.The other parts of the program can run smoothly and meet the requirements of the measurement experiment.Finally,the PC software is applied to the experimental measurement of the pool acoustic characteristics measurement system.Through the construction and testing of the whole pool measurement system,the function and operation ability of the upper computer software are tested.The experimental results show that the software algorithm of the host computer has correct function and smooth operation,which meets the display and control requirements of the pool acoustic characteristics measurement system and can be transplanted to the actual engineering needs.
