The Application of Single Vector Sensor in Direction Tracing of Water-entry Object

Abstract

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.
