1.引言现代飞行器,往往要有天线和天线罩。就天线罩本身而言,它既是飞行器壳体的一部分,又是雷达系统的一部分。天线罩既然是飞行器壳体的一部分,它就得满足气动力性能、结构及强度、环境等方面的要求;天线罩又是雷达系统的一部分,它就得满足一定的电性能要求,即天线罩应对天线的影响最小。然而,天线罩的电性能指标与天线有密切关系,因此应把天线和天线罩作为一个整体来考虑,即应考虑天线-天线罩组合的电性能。天线-天线罩
1. Introduction Modern aircraft often have antennas and radomes. For the radome itself, it is both part of the aircraft’s shell and part of the radar system. Since the radome is a part of the aircraft shell, it has to meet the aerodynamic performance, structure and strength, the environment and other requirements; radome is a part of the radar system, it has to meet certain electrical performance requirements, namely radome The effect on the antenna should be minimal. However, the electrical performance of the radome is closely related to the antenna. Therefore, the antenna and radome should be considered as a whole. That is, the electrical performance of the antenna-radome should be considered. Antenna - Radome
