ABSTRACT
ABSTRACT: Themarine electric field observation technology is widely used in themilitary field such as subsea oil and gas hydrate exploration as well as the electric field detection of warship. To achieve low noise detection of weak seafloor electric signals, one of its key technologies is the low noise marine electric field sensor. For a group of electrolysis technology developed electrodes, in order to detect whether they meet the expected targets, it is necessary to carry out a comparison test for its various techniques. Our test gives an evaluation mainly on signal conversion capability, difference potential stability and self-noise of the electric field sensor. Through establishing a series of test solutions, the original test results of different electrodes were gotten. The analyzed results show that the electrode fully achieve the expected goals, it also proves the effectiveness of the test solution.
