电磁场对航空电子设备干扰的预测研究

论述飞机内部辐射电磁通过电缆线感应耦合，形成对电子设备干扰的机理，分析这种干扰模式既有辐射，又有传导的复合特点。应用孔缝衍射、场对线激励、含分布源传输线和网络分析等理论与方法，逐层剖析描述了预测数学模型，并给出了能够对电子设备电子元件级进行可靠性和安全性评估的实用预测软件。

STUDY ON THE PREDICTION OF ELECTROMAGNETICFIELD INTERFERENCE ON AVIONICS

The mechanism of the avionics being interfered by the inside electromagnetic fieldthrough wires inductive coupling. This interference mode has both the radiation and transmission features. The theories and methodologies of aperture diffraction, field-to-wire excitation, transmission line with distributing voltage source. and circuit analysis are applied to establish the prediction model. The practical computer program is developed to evaluate the reliability and safety of avionics and electronic components.
