【 摘 要 】

In the report an applicationof the pulse method is presented for hydroacoustic test tank measurements. The basic test tank hydroacoustic equipment is from Bruel&Kjaer with National Instruments based control and measurement hardware and software platform. A LabVIEW software is used for synthesis, transmission and measurement of acoustic signals with different pulse lengths and intra-pulse modulations. A number of VI's are designed for digital signal processing and visualization of the signals and results. Capabilities are shown for test tank measurements of sonar transducers pattern and quality factor.
