摘要

本文讨论了波音707飞机上30 ~ 500 MHz叶片天线安装性能的电磁仿真验证。用于验证的参考天线方向图数据来自对波音707飞机1:25比例模型的测量。叶片天线采用宽带谐振单极子建模。描述了在500米长的地面反射天线范围内测量的偏航、横摇和俯仰模式。在电磁软件包FEKO中建立了波音707的数值模型。结果发现，考虑到测量设置中建模和公差的细微差异，测量结果与模拟结果比较非常好，从而验证了模拟结果。

Validation of a computational electromagnetic model of a boeing 707 aircraft by comparison to scale model measurements

The validation of electromagnetic simulations of the installed performance of 30 to 500 MHz blade antennas on a Boeing 707 aircraft is discussed in this paper. The reference antenna pattern data for the validation is obtained from measurements made on a 1:25 scale model of a Boeing 707 aircraft. The blade antennas are modeled by means of broadband and resonant monopoles. The yaw, roll and pitch patterns as measured on a 500 m long ground reflection antenna range are described. A numerical model of the Boeing 707 was developed in the electromagnetic software package FEKO. It was found that taking into account slight differences in modeling and tolerances in the measurement setup, the measured results compared very well to the simulated results thereby validating the simulations.
