摘　　要：针对开阔试验场进行电磁兼容性船模试验易受环境影响的缺点,提出了基于电波暗室的船模预测新方法.根据电磁缩尺模型理论,推导出预测天线端感应电压、天线耦合度2个重要参数与缩尺比之间的关系,以模型天线近场测量为重点,介绍了模型预测的实现.理论分析和试验比较表明,利用电波暗室作为模拟场地进行船模预测是可行的,它具有全天候、环境好的特点.In view of the fact that electromagnetic compatibility （EMC） prediction method used by scaled ship model in an open area test site is easy to be affected by outside environment, this paper put forward a new scaled ship modeling method based on anechoic chamber. According to the theory of electromagnetic scaled model, this paper deduced the relations of scaled ratio with inducting voltage on antenna terminal and antenna coupling. By the conditions of model test, the realization of the model prediction was introduced with emphasis on the near field strength measurement of model antenna. Through the comparison between the theory and test analysis, it is feasible to use anechoic chamber as the test site of EMC prediction for the scaled ship model. It possesses the characteristics of all weather and good environment, etc.
