| 天线隔离度是机载电子系统实现电磁兼容预测的重要参数。根据
反应积分原理，提出采用孤立天线远场方向图来替代实际环境中天线的办法，简化分析模型
，在保证分析精度的基础上，提高计算效率，从而高效完成电大尺寸环境中天线隔离度的仿
真分析。通过在自由空间情况下进行测试，验证了仿真结果的准确性。 |

| Abstract: |
| The coupling between antennas is an important parameter for describing the elect
romagnetic in
terference(EMI) of the airborne electronic systems. Based on the integration the
ory, the
far field radiation pattern is replaced for the antenna model, and then the airb
orne model is considered at the same time. This method can be applied to simplif
y the model and improve the efficiency with proper precision for the analysis an
d p
rediction of airborne antenna isolation. Measurement results in free space are p
resented to validate the simulation results. |
