Abstract : the single toroidal non - reciprocal ferrite phase shifter that isthe key components of a phase array antenna is studied to develop the phase array antenna for autotracking synchronous communication satellite 文摘:为了研制自动跟踪同步通信卫星平板相控天线阵系统,对相控阵天线中的关键元件单环非互易铁氧体移相器进行了研究。
The key for phased array antennas with good functions is the use of controllable phase shifters . however , phase quantization errors affect the accuracy of phased array antenna beam pointing badly , which is mainly researched here 其中可控数字移相器的使用,是相控阵天线优越性能实现的关键,但由此引入的相位量化误差,严重影响了相控阵天线的波束指向精度。
Floquet ports : these periodic ports enable designers of phased - array antennas and frequency - selective surfaces to obtain separate fields into modes for better understanding and examine phase information for each mode 傅里叶端口:这种周期性的端口可以使相控阵天线和频率选择表面的设计者能够得到不同传输模式下的场型,从而能够更好地理解和验证每种模式下的相位信息
Based on the requirement , a base station array antenna of which beam width in h - plane is 45 is made . the relationship between the size and the performance of array antenna is researched . the antenna is tested and is proved eligible 根据实际要求,设计一副水平面波瓣宽度为45的基站阵列天线,讨论天线尺寸与性能指标的关系,对天线进行测试,达到了设计要求。
The mutual coupling between phased array antennas elements causes the loss of reflected power . following the changes of scanning angle , mutual coupling between elements will also change , so the comensation of mutual coupling should become difficult 相控阵天线单元间由于互耦效应引起的反射功率损耗,随着扫描角的变化而随之发生变化,这给互耦补偿带来了极大地困难。
By dividing the large array antenna into a set of virtual subarray antennas , the receivers are connected to each subarray via a program - controlled switch based on time - division - multiplexing , and process the output snapshots on the subarray - antenna 阵列天线划分为虚拟子阵列,基于时分复用工作方式,通过程控交换矩阵与接收机连接,接收机对不同虚拟子阵列天线输出信号分时进行接收处理。
