【摘要】 嫦娥三号是国内首个地外天体软着陆探测器和月面巡视探测器.探测器在月表选定的区域成功实施软着陆,着陆器开展就位探测,巡视器开展巡视勘察,巡视器的探测数据可以直接传回地面站或通过着陆器转发传回地面站.为实现嫦娥三号探测器巡视器对着陆器的数据传输,嫦娥三号探测器设计了UHF频段月面通信系统,在月球表面成功实现了UHF频段器间通信技术的在轨试验.本文主要对嫦娥三号探测器UHF频段月面通信系统方案、通信链路衰减分析以及地面试验验证情况进行说明,并对月表开展的在轨验证情况进行介绍.更多还原

【Abstract】 The Chang’E-3 is the first Chinese soft landing lunar probe, including a lander and a rover. After landing on the certain area of lunar surface, lander started in-situ exploration, rover began lunar surface reconnaissance. Data of rover exploration can be transmitted via direct-to-earth link or relay link of lander. UHF lunar surface communication system is designed for transmitting data from rover to lander. The system achieved the on-orbit verifications goal of lunar surface transmission successfully. The paper describes the design of the Chang’E-3 probe lunar surface communication system, transmisson loss analysis, tests on the ground, and the on-orbit verifications.更多还原
