Abstract

The invention belongs to the technical field of marine electromagnetic detection, and discloses a marine electromagnetic field signal acquisition system, device and a marine environment observation system. The system comprises an electric field signal acquisition unit, a magnetic field signal acquisition unit, an azimuth attitude signal acquisition unit, a platform magnetic field signal measurement unit and a main control unit. The system can realize a detection mode of combining an electric field and a magnetic field; a magnetic field generated by movement of the mobile platform and a magnetic field generated by internal parts of the platform can be compensated; and various magnetic field measurement modes including independent magnetic field acquisition, tensor type magnetic field acquisition and zero magnetic tensor type magnetic field acquisition can be supported. The electric field signal acquisition unit, the magnetic field signal acquisition unit, the azimuth attitude signal acquisition unit, the platform magnetic field signal measurement unit and the main control unit all adopt low-noise design. Collection of weak low-frequency electric field and magnetic field signals in the marine environment can be achieved, and the system can be used for marine environment background electromagnetic field measurement and marine environment underwater target detection.

Description

technical field [0001] The invention belongs to the technical field of marine electromagnetic detection, and in particular relates to a marine electromagnetic field signal acquisition system, a device and a marine environment observation system. Background technique [0002] At present, marine environmental observation is the basis and an important part of integrated ocean management, providing a scientific basis for integrated ocean management. The marine environment observation system has played a huge role in the development and utilization of the ocean, environmental protection, disaster warning, national defense and security. The marine environment observation system is divided into three categories: space-based, shore-based and sea-based according to the spatial location. The sea-based marine environmental observation system consists of buoys and submersibles, surface survey ships, submarine observation platforms, and unmanned mobile observation platforms. The observ...
