| 摘 要： | The double-peak characteristic of underwater radiated noise in the near field on top of the target submarine was analyzed in depth on the basis of submarine test data on the sea. The contribution of three major noise sources to the radiated noise of a submarine were compared and analyzed, and emphasis was put on the original source, production mechanism, and their correlative characteristics. On the basis of analysis on underwater tracking and pass through characteristics of the target submarine, the double-peak phenomenon was reasonably interpreted. Furthermore, the correctness of the theoretical interpretation was verified adequately in real submarine tests. The double-peak phenomenon indicates that the space distributing character on submarine radiated noise are both asymmetrical with time and space, whereas that is provided with directivity. Studying the double-peak phenomenon in depth has important reference value and meaning in engineering practice for understanding the underwater radiated noise field of submarines.

| Abstract: | The double-peak characteristic of underwater radiated noise in the near field on top of the target submarine was analyzed
in depth on the basis of submarine test data on the sea. The contribution of three major noise sources to the radiated noise
of a submarine were compared and analyzed, and emphasis was put on the original source, production mechanism, and their correlative
characteristics. On the basis of analysis on underwater tracking and pass through characteristics of the target submarine,
the double-peak phenomenon was reasonably interpreted. Furthermore, the correctness of the theoretical interpretation was
verified adequately in real submarine tests. The double-peak phenomenon indicates that the space distributing character on
submarine radiated noise are both asymmetrical with time and space, whereas that is provided with directivity. Studying the
double-peak phenomenon in depth has important reference value and meaning in engineering practice for understanding the underwater
radiated noise field of submarines. |
