萤火一号火星探测器深空天线设计技术

Deep Space Antenna Design for YH-1 Mars Probe

根据分系统指标需求,对萤火一号(YH-1)火星探测器天线设计进行了研究。给出了天线的功能与技术指标。介绍了对高增益天线、低增益发射天线与低增益接收天线的方案和结构设计。天线测试结果表明三种天线均满足指标要求。分析了材料选用等环境适应性设计。冷热交变、深冷低温及太阳照射等试验结果验证了设计的天线在深空探测环境中的可靠性和适应性。

According to the system requirement, the design of deep space antenna for YH-1 Mars probe was studied in this paper. The function and performance of the antennas were given out. The scheme and structure design of high gain antenna, low gain transmit antenna and low gain receive antenna were introduced. The test results of the antennas designed showed that the three antennas would meet the requirement. The environment suitability design including material selection was analyzed. The results of the high-low temperature test, ultra-low temperature test and solar exposure test approved the reliability and suitability of the antennas designed in deep space environment.
