在舰船水下电磁场测试中对海洋环境水下电磁场干扰程度进行量化分析,以提高舰船水下电磁场测试精度。通过增加环境监测单元,本文提出了环境电磁场空间匹配算法,进而确定了舰船水下电磁场测试中环境电磁干扰量化分析方法。根据海上实测结果,验证了该方法的可行性。舰船水下电磁场测试中,海洋环境电磁场引起的误差不可忽略,应在量化分析基础之上,采取有效的抑制和规避方法。
In order to improve the accuracy of underwater electromagnetic field test, the underwater electromagnetic field interference in marine environment is analyzed quantitatively. By adding the environment monitoring unit, this paper proposes the space matching algorithm of the environment electromagnetic field, and then determines the quantitative analysis method of the environment electromagnetic interference in the underwater electromagnetic field test. The feasibility of the proposed method is verified based on the measured results at sea. In the underwater electromagnetic field testing of ships, the error caused by the electromagnetic field in the marine environment can not be ignored. Based on the quantitative analysis, effective suppression and circumvention methods should be adopted.
