摘要
天线罩在保护雷达天线不受环境影响的同时,又会对天线的电磁辐射产生某些干扰,改变天线的电气性能。利用电磁场数值计算方法研究了在因气动、机械强度和耐热性等因素而需改变天线罩的厚度或材料的介电常数等相关参数时对天线方向图的影响,作为天线和天线罩的电磁相容性研究的参考。
Radome is designed to protect the radar antennas from the external environment. However, radome is interfering with the electromagnetic radiation of radar antenna, which may result in significant performance change to radar antenna systems. The influence of radome＇s parameter, such as thickness, dielectric coefficient, altered being air-powered, mechanical robustness and heat-durability on antenna radiation pattern is analyzed by numerical method of electromagnetic field. This lays a good function for the future research on combined design of antenna and radome system.
