技术领域Technical field
本发明涉及天线结构设计技术领域，更具体地，涉及一种S/X/Ka三轴天线。The present invention relates to the technical field of antenna structure design, and more specifically, to an S/X/Ka three-axis antenna.
背景技术Background technique
卫星数据接收天线一般用于完成各类卫星下行数据的接收，根据星地链路需求，星地链路测算的卫星信号信噪比需大于卫星信号解调门限要求。为适应不同卫星接收需求，地面接收天线一般要求采用较大口径的天线，以Ka频段为例，遥感卫星数据接收天线一般要求G/T值大于40dB/K，对应的天线口径为12米。常规12米Ka频段天线结构重量往往超过50吨，是一种大型天线。Satellite data receiving antennas are generally used to receive various types of satellite downlink data. According to the requirements of the satellite-ground link, the signal-to-noise ratio of the satellite signal measured by the satellite-ground link must be greater than the satellite signal demodulation threshold requirement. In order to adapt to different satellite reception needs, ground receiving antennas generally require larger diameter antennas. Taking the Ka frequency band as an example, remote sensing satellite data receiving antennas generally require a G/T value greater than 40dB/K, and the corresponding antenna diameter is 12 meters. The structural weight of a conventional 12-meter Ka-band antenna often exceeds 50 tons and is a large antenna.
随着国家空间基础设施的规划，各类卫星迎来了蓬勃的发展，地面接收能力的建设逐步由国内转向境外，现有的大型天线在境外(如极地地区)进行建设时，存在设备重量过大的问题，条件受限时将无法完成转运。如极地地区在冰层融化厉害时，将需要利用直升机实现转运，此时要求转运单件设备重量不超过4吨。此外部分境外站存在条件艰苦、供电受限、建设时间短等问题，需减少现场安装部署的时间，实现快速安装。With the planning of national space infrastructure, various types of satellites have ushered in vigorous development. The construction of ground receiving capabilities has gradually shifted from domestic to overseas. When existing large antennas are constructed overseas (such as polar regions), there is an excessive weight of the equipment. Big problem, the transfer will not be completed when conditions are restricted. For example, when the ice melts severely in the polar regions, helicopters will be needed for transportation. At this time, the weight of a single piece of equipment for transportation is required to not exceed 4 tons. In addition, some overseas stations have problems such as difficult conditions, limited power supply, and short construction time. It is necessary to reduce the time for on-site installation and deployment to achieve rapid installation.
