Water-entry signal was important to broadcast the water-entry object. The vector sensor could gain the pressure and particle velocity signal, so the azimuth angle of water-entry signal could be estimated by single vector sensor. The complex sound intensity method was applied in vector signal processing in azimuth estimation. The estimated deviation in different SNR was give out via simulating experiment. The method was used in the experiment on the lake and was proved to be effective.

Automatic Positioning

This paper presents the procedure for measuring the sound intensity. The procedure was realized in such a way that therobotic arm carries the intensity probe and performs automatic positioning at the appropriate measurement points. In order todetermine the deviation value, a comparison was performed of sound intensity measurement obtained using robot and the measurementmanually performed by two people. Also, the measurement process was repeated for both the automated and manual positioning of theprobe, which resulted in deviation values for these two types of measurements. The differences in the total sound power of the sourceobtained by automated and manual measurements of the sound intensity were also analyzed. Using a robot arm significantly facilitatesthe measurement process and achieves higher measurement accuracy. Such use of robots can be of interest in measuring the intensity ofsound of complex sound sources in a large number of points, where high accuracy of intensity measurement is required.
