摘要
随着洲际弹道导弹、潜射弹道导弹、多弹头分导再入式导弹等进攻性武器和各种卫星的发展,对覆盖距离远、分辨率高、跟踪目标多的多功能探测系统装备——大型相控阵雷达的需求日益增加。近年来,大型相控阵雷达得到了长足的发展,远程预警雷达、远程相控阵雷达、远程防空监测雷达等均已完成阵地布设。不同的天线阵面安装结构形式对雷达装备的架设、阵面精度的控制带来了不同的影响。文中通过对比2部大型固定式相控阵天线阵面安装与阵面精度控制过程,分析了过渡骨架和调整机构2种连接结构形式对天线阵面的安装与精度控制的影响,阐述了两者的优劣之处,对今后大型相控阵雷达的高效、低成本研制和部署具有借鉴意义。
Along with the development of strike weapons( such as intercontinental ballistic missile,submarine launched missile,MIRV missile) and various satellites,the demand on the large multifunctional detection system namely the large phased array radars,has been increasing rapidly for its advantages of vast coverage &long range,high resolution and multiple target trail. In recent years great progress has been made in the large phased array radar. The long-range early-warning radar,long-range phased array radar and long-range air defense monitoring radar have been deployed at radar sites. Different installation structural forms of antenna array have different effects on radar installation and accuracy control of array. In this paper,the effects of two connecting structural forms( transition skeleton and adjusting mechanism) of two antennas are analyzed upon installation and accuracy control by comparing the installation process and accuracy control process of antenna arrays for two large stationary phased array radars. According to the comparison result,the merits or demerits of each antenna arrays are concluded. It can be used as reference for future development and deployment with high efficiency and low cost of large phased array radars.
