摘要
系统地分析研究了舰船总体电磁兼容性(EMC)数模分析预测软件的建模原理、分析预测功能和工程应用,着重讨论了舰上发射机和非线性结构的"锈蚀螺栓效应"的互调产物等干扰源的数学模型。由于舰船电磁环境的复杂性,预测软件应能够对多参数进行分析。本文详细介绍了该软件的4个模块:天线最佳布置性能分析模块、电缆耦合干扰分析模块、各设备(或分系统)间电磁兼容性分析模块、大功率设备辐射近场场强分布分析模块。工程实践证明,该软件预测精度满足要求。
The paper introduces the software function and the application. The model of sensors as of naval ship EMC, including the model theory, the inter-modulation interference that has been brought by the rusty-boh effects of the onboard transmitters and non-linear structure has been discussed. Owing to the complex of electromagnetic environment for ship, the software should obtain some kinds of parameters. There are four modules that have been introduced including ATACAP, WTWCAP, STSIAP and EENFAP. The results from the application indicate the accuracy of the software satisfies the requirements of measurement.
