Abstract

Fiber laser hydrophone has attracted more and more attention because of its potential application in novel sonar system. For a towed fiber optic hydrophone array, the flow noise is an important source of the system noise. This paper presents the field test result of the flow noise of an eight-element fiber laser hydrophone array. The structure of the fiber laser hydrophone and the array is also introduced. The field test shows that obvious flow noise can be measured when the array is towed at the speed of 3 kn.
