航空通信系统试飞过程中的电磁兼容性评估

电磁兼容性(EMC)是航空电子产品的主要性能，也是实现系统功能的重要保证。试飞试验是 按照预想实现一种思想而提供最终证据的在机载真实环境条件下进行飞行试验，并通过试飞 数据分析结果评估系统效能，所以，EMC预测是航空电子系统试飞评估主要内容之一。论述 了基于电磁拓扑（Electromagnetic Topology）理论分析的航空通信系统EMC评估方法，该 方法已在航空通信系统试飞中被采用。

Electromagnetic compatibility evaluation in test flight of avionics communication systems

Electromagnetic compatibility (EMC) is the main performance of avionic electronic products and an important guarantee for the realization of system fu nctions. Flight test is to verify some expected idea by providing data acquired from real flight conditions, and the test performance is analyzed and evaluated by the results of flight test data. Therefore, EMC prediction is one of the main contents in test flight of avionic communication systems. The EMC evaluati on method based on electromagnetic topology(EMT) is discussed in this paper.The proposed method has been used in avionics communication system flight test.
