The variable phase center is defined for general linear array, which makes that the directive antenna can be used as elements of the interferometer array. 为了能把不存在相位中心的定向天线单元应用到干涉仪测向系统,提出了可变相位中心概念,并给出了对数周期偶极子天线可变相位中心计算实例。
The antenna system consists of three parts: an assembly of the omnidirectional telemetry and command antennas, a directive communications antenna and a three channel noncontacting rotary joint. 该天线系统包括三部分:全向遥测遥控天线组件,定向通信天线和三信道无接触旋转关节。
Calculation of the directive function and the gain of concealed conical scanning antenna 隐蔽锥扫天线方向函数和增益的计算
