摘要: 由于无人机的内部空间狭小,设备安装拥挤,使得无人机系统内电磁环境相当复杂,恶劣的电磁环境导致设备间产生严重的干扰问题。因此,要保证无人机机载通信设备间的电磁兼容性,电磁兼容预测是一种非常有效的手段。本文根据无人机的特点,提出一种适用于无人机机载通信设备间射频电磁兼容性预测的干扰余量分析法。通过对设备进行频率预测和幅度预测,验证这种方法的有效性,从而为分析机载通信设备间的射频电磁兼容性提供一套有效方案。

关键词: 电磁兼容性, 预测, 干扰余量

Abstract: As the internal space of UAV is limited and the equipments are closely installed, the electromagnetic environment of UAV system is fairly complex and the deteriorative electromagnetic environment causes serious interferences among different equipments. Therefore, electromagnetic compatibility prediction is a very effective means to ensure the electromagnetic compatibility among the UAV airborne communication equipments. According to the characteristics of UAV, an interference margin analysis method is proposed, which is fit for the RF electromagnetic compatibility prediction among the UAV airborne communication equipments. The effectiveness of this method is verified by the mathematical model of the airborne equipments about frequency and amplitude forecasting, which provides an effective solution for analyzing the RF electromagnetic compatibility among airborne communication equipments.

Key words: electromagnetic compatibility, prediction, interference margin
