Abstract In order to improve the efficiency of analysing hydroacoustic transducer sound field, the research focusing on reconstruction method of hydroacoustic transducer sound field was developed based on near-field measurement. Firstly, the holographic measuring surface of hydroacoustic transducer was seemed as source surface, which made it realizable to obtain the sound field reconstruction model by integration. Then, took advantage of self-developed underwater acoustic measurement system to obtain the complex sound pressure of emission transducer at holographic measuring surface, according to which sound field was reconstructed. And finally, as well as ascertaining a valid measurement interval for the reconstruction method by comparing the different reconstruction results of holographic measurement surface and measured data and analyzing the impact of the holographic measurement plane position on reconstruction error. The sound field reconstruction method could obtain the field distribution of hydroacoustic transducer quickly, and it is accurate and reliable.
