With the new radar antenna encased within a radome , the radar system can work continuously under all weather conditions even during typhoon . the radar antenna measures 9 . 7 metres high and 13 . 7 metres wide , while the radome has a diametre of 15 metres 新雷达天线装置于天线罩内；雷达系统因此能于任何天气，甚至在台风吹袭下持续运作。雷达天线高九点七米，阔十三点七米；天线罩直径则为十五米。
The radome design techonic is one of the key techonics in development of a radar - homing air - to - air missile , in development of the radome , the initially designed radome was structurally failed in a ground thermal - structural test 雷达型空空导弹研制过程中，天线罩的设计技术是关键技术之一。在某雷达型空空导弹天线罩研制中，其最初方案在地面静热强度试验时，天线罩结构被破坏而导致设计方案失败。
Radome is designed to protect the antennas from the external environment . however , radome is interfering with the electromagnetic radiation of antenna , which may result in significant degradation of antenna performance , cause transmission attenuation and beam deflection 天线罩在保护天线不受外界影响的同时对天线的电磁辐射产生某些干扰,使天线的电性能降低,引起天线的传输损耗和波束偏移。
With the development and application of the microwave communication system 、 precision guided technologies and electronic countermeasure etc , the research on dielectric materials such as circuit dielectric substrate 、 antenna unit dielectric substrate and radome are paid more and more attention 随着毫米波通信系统、精确制导、电子对抗等技术的发展和应用,对电路介质基片、天线单元介质衬底、天线罩等介质材料的研究越来越受到重视。
The missile with its radome is at high temperature during the entrance . due to aerodynamics heating process , the high temperature cause air ionization and ablation of the radome , so the radome is at unsymmetrical heat environment , its electrical properties vary with different parts of the radome 导弹在再入过程中,由于空气动力加热效应,引起空气电离和天线罩表面被烧蚀,因此,天线罩处于不对称热环境中,它各部分的介电性能不同。
On the basis of the situation analysis for practical engineering application , it is put forward to add compensating measures in airspace circuit including instruction feedforward , target feedforward , carrier aircraft feedforward and radome refraction compensation to improve the airspace stabilization accuracy 根据实际工程应用中的情况分析，为提高空域稳定精度，提出了在空域稳定回路中加入补偿措施，即指令前馈、目标前馈、载机前馈和天线罩折射补偿。
The radiation patterns with and whitout radome are calculated , and the angle difference in the maximum field point of their main clot show the bse of the radome , the bse from - 15 degree to 15 degree in direction , that been calculated and compared with the excited experimented data shows they coincide quite well 有天线罩时的远区场和没有天线罩时的远区场相比较,两个主波束对应的角度差即是天线罩的瞄准误差,本文对方位扫描角从负15度到正15度进行分析。
It is suitable to be used as the medium to filter the high purity and strong corrosive gas or liquid , the air plug of battery , gasket , seals for medium / low pressure , the waveguide tube pre - heater for boiler , the sealing wash , the cover of big - powered micro - wave antenna , and radar antenna of twt etc 适用于过滤、高纯度、强腐蚀性的气体液体介质、蓄电池上作气塞、衬垫、中低压密封元件、锅炉波管预热器、密封圈和军用微波大功率天线罩，以及行馈网络雷达天线等。
According to the requirement of precision grinding , a design scheme for the equipment that has dual - station for both measuring and grinding on the same machine is adopted . a cnc control system satisfying the control needs for precision measuring and grinding is developed , which is composed of double cpu comprising of an industrial personal computer ( ipc ) and a programmable multi - axis controller ( pmac ) , with closed control loops and perfect electromagnetic compatibility ( emc ) 根据天线罩的精密修磨加工要求，确定采用“一体式双工位测量与加工”的装备设计方案，研制了满足精密测量与修磨加工控制要求的cnc控制系统，该系统采用由工业控制计算机和多轴运动控制器组成的双cpu结构、全闭环控制方式，并具有完善的电磁兼容性设计。
