Abstract | 阵列接收机是将其前端阵列天线放置于射电望远镜焦平面处,结合后级波束合成网络以形成多个连续波束,用以同时观测一片连续天区、实现更大视场覆盖的接收机技术。本文理论设计了工作在1.25 GHz的十六阵元矩形排布贴片天线阵列,并在该贴片天线阵列样机的基础上进行了实验室测试。在等幅激励、30°设计扫描角度配相下,实测的阵列主波束增益为14.03dBi、扫描角度约为35°。测量结果显示该贴片天线阵列满足设计指标,相关工作对阵列天线的模拟波束合成及扫描性能验证也具备较好的指导意义。 |
Other Abstract | Array receiver is a receiver technology that places its front-end array antenna at the focal plane of the radio telescope and combines with the subsequent beamforming network to form multiple continuous beams to observe a continuous sky area at the same time and achieve greater field of view coverage. This article theoretically designs a sixteen element rectangular patch antenna array operating at 1.25 GHz and laboratory testing was conducted on the basis of the prototype of the patch antenna array. Under equal amplitude excitation and 30 degrees design scanning angle phase matching, the measured main beam gain of the array is 14.03 dBi, and the scanning angle is about 35 degrees. The actual measurement results show that the patch antenna array meets the design specifications, and the related work also has good guiding significance for the simulation beamforming and scanning performance verification of the array. |
