摘要
海洋环境电场是探测水中目标的主要干扰源之一。初步探索了海洋环境电场24 h的变化规律。对测试数据进行拟合,可以预测不同时间点上的环境电场强度。通过分析知道,影响环境交变电场的主要因素是工频电场,比较了工频电场剔除前后幅度变化的规律。
Electric field of marine environment is one of important interfering sources of underwater target detection. Variable pattern of electric field of marine environment for twenty-four hours was explored from data analysis. Intensity of electric field of marine environment in different time was estimated through data fitting. I was founded that essential component of the electric field is industrial frequency after interpretation of result. Amplitude of alternative electric field was compared before and after pick out electric field of industrial frequency.
