Abstract :
The choice of algorithms and the hydrophone array is the key of getting high precision in underwater targets detection. Using LabVIEW and 8 channel data acquisition card the underwater targets noise was gathered. Based on the MATLAB, the algorithms of underwater targets estimation have been confirmed. The water tank experiments have shown that this system can realize to acoustic signal gathering, processing. The results obtained in this paper can give reference for array shape and algorithms selection .
