英文摘要： Marine electromagnetic detection technology has been widely applied as an important adjunct method in western countries in recent years. The prominent issue is that electric field signal is too weak for detecting in the marine environment.This asks for the extreme demands of the undersea electric field sensor performance. The objective of this project is to reduce the noise of undersea electric field sensor.The electrode performance impact factor analysis will be sudied and the electrode production process will be improved. Electrochemical characteristics of the electrode material and proportion and combinations of the electrodes will be studied. The sensor test platform will be built to optimize the sensor design and improve electrode craftsmanship. A set of manufacturing processes and evaluation methods will be put forward. The successful implementation of this project will provide high-performance sensors for marine magnetotelluric and controlled source electromagnetic detection. It also has important practical value and broad application prospects.
