摘要
对萤火一号(YH-1)火星探测器高灵敏度模拟接收机技术进行了研究。给出了模拟接收机的主要功能和组成,介绍了降低接收机噪声系数,减少接收机带宽等关键技术。阐述了中频锁相、指令解调等模块的工作原理,列出了研制的高灵敏度模拟接收机的主要性能指标。
The technology in high sensibility analog receiver of YH-1 Mars probe was studied in this paper. The main function and composition of the receiver were given out. The key technologies such as reducing the noise factor and bandwidth of the receiver were presented. The principles of the intermediate frequency phase lock and command demodulation were put forward. The capability parameters of the receiver were given.
