摘要
针对分布式星簇(或星群)内部各卫星之间的数传及组网通信的应用需求,基于需要研究工作在X频段上具有良好方向回溯性的方向回溯天线的目的,本文采用超外差混频技术的方法研究开发了工作在8.1 GHz上的一维方向回溯天线。通过对其在暗室中进行单站RCS和双站RCS测试,结果显示,在喇叭天线主波束±30°范围内,回波电平的波动在3 dB以内,且回波接收最大的方向确实出现在问讯信号(入射信号)方向,天线的指向误差控制在±3°以内,具有良好的方向回溯性能,满足设计指标。
Be based on research of superheterodyne mixer technology,a one-dimension X-band retrodirective antenna working on8.1GHz has been developed,to meet the demand of developing a kind of retrodirective antenna with a good retrodirective capability and to satisfy the need of data transmission and communication between the satellites inside a distributed satellite clusters.According to Monostatic and Bistatic RCS Measurement in microwave anechoic chamber,results show that the fluctuation of echo power is within3dB in the ±30°range of horn antenna’s main beam and the direction of the maximum echo reception indeed appeared on the direction of the incoming signal and the Beam Pointing Error(BPE)is within ±3°,which proves that the antenna we designed has a good retrodirective capability.
