摘要
GJB151A/152A是1997年制定的标准,至今已有10年之久,像RS103中关于舰船电场场强的极限值是否仍然适用值得研究。本文利用电磁仿真软件FEKO,对舰船舱室进行了建模以及舱室内电磁环境的仿真计算,得出了舰船电磁环境随舰船甲板上天线数、天线到舱室距离以及天线发射功率变化的规律,给出了其依赖关系,并以此为依据提出了国军标GJB151A/152A中关于RS103辐射敏感限值的初步修正意见。
It has been over 10 years since the military standards GJB151A/ 152A were published in 1997.Thus their applicability is worth studying,such as the item of RS103 used for surface ship.The model of the shipboard cabin was developed and the electromagnetic environment（EME）in it was simulated by using the electromagnetic field analysis software FEKO.The EME in the shipboard cabin varying with the number of antennas on deck,the distance between the antenna and cabin,and the transmitting power of antennas was obtained,and their dependent relations were also presented.On the basis of that study,the preliminary amendment suggestion on RS103 in GJB151A/152A was given out.
