Abstract: A signal cable integrated acoustic sensor line array system is provided to prevent an external pressure from being delivered to an acoustic sensor assembly by seamlessly integrating the acoustic sensor on a signal cable. A signal cable integrated acoustic sensor line array system comprises a signal cable and plural acoustic sensor assemblies. The signal cable includes a high-tension member, a signal line, and a power line. The acoustic sensor assemblies are arranged along the signal cable and integrated with the signal cable. The acoustic sensor assembly detects an underwater sonic signal. The acoustic sensor assembly includes an underwater sound collector assembly(10), a water-tight connector(11), an integrated mount(12), and a protective cover(13). The underwater sound collector assembly converts an underwater sonic signal to an electric signal. The water-tight connector delivers acoustic signals between the signal cable and the underwater sound collector assembly. The water-tight connector is attached to the integrated mount. The protective cover encloses the underwater sound collector assembly and the integrated mount.
