舰船编队EMI分析中不定因素的研究

舰船编队的电磁干扰（EMI）分析预测比单舰情况复杂，这是由于编队中各舰相对运动产生的不定因素对预测结果会产生一定的影响。具体讨论了编队中舰舰间距离、方位和雷达天线转动等不定因素的扰动对耦合度的影响，提出了在舰船编队电磁兼容性分析预测中应采用统计分析技术。

Discussion on uncertainty factors in EMI analysis of the fleet formation

EMI prediction on the formation of ship is more difficult than on a single ship. Some uncertainties, which is produced due to its relative move of ship in the formation, provides some impacts on precision of the analysis. These factors consist of the distance and the positions between ships, as well as rotation of radars. The coupling disturbed by these factors is discussed concretely in this paper. It points out that statistical method can be used in EMC analysis of the fleet formation.
