摘　　要：对萤火一号(YH-1)火星探测器的X波段深空指令接收机设计进行了研究。给出了接收机设计原理、技术指标与技术特点。介绍了射频前端的变信道功能、极高的频率稳定度和收发隔离,以及中频处理单元的微弱信号捕获与跟踪、信号解调等设计。设计的接收机具有小体积、轻质量、低功耗和长寿命等特点。电性能测试和对接试验结果表明:接收机设计合理,符合技术指标要求,能满足YH-1火星探测器的应用要求。A small X-band deep space digital uplink receiver for YH-I Mars probe was developed in this paper. The principle, performance and characteristics of the receiver were given out. The channel changing function, very high frequency stability and transceiver isolation of the RF front, and faintness signal capturing and tracing, and demodulation of mid-frequency unit were introduced. The receiver designed was small volume, light mass, low power and long life. The results of the electrical performance test and linking test showed that the receiver was reasonable design and met the requirements, which＇could be applied in YH-1 Mars probe.
