【摘要】：海洋环境水下电场是装备测试中的重要背景场,由于背景电场的频谱叠加,装备测试精度受到严重影响。本文利用时域、频谱和时频分析相结合的方法,研究了海洋环境水下静电场、交变电场和工频电场的基本特征。基于研究成果,指出了装备测试时应避免海水运动剧烈、磁暴和雷电等特殊环境条件并选择在凌晨1:00~3:00时间内进行测试。
[Abstract]:Underwater electric field in marine environment is an important background field in equipment testing. Because of the spectrum superposition of background electric field, the precision of equipment testing is seriously affected. In this paper, the basic characteristics of underwater electrostatic field, alternating electric field and power frequency electric field in marine environment are studied by means of time domain, frequency spectrum and time-frequency analysis. Based on the research results, it is pointed out that special environmental conditions such as severe sea water movement, magnetic storm and lightning should be avoided in the equipment test, and the test should be carried out at 1: 00 to 3: 00 in the morning.
