在“嫦娥1/2/3号”系列探测任务中开展了行星无线电科学探测实验,这些工作包括:使用天文VLBI技术对探测器进行工程和科学测轨、定位观测,开环和闭环测速测距观测,基于微波观测重构和优化月球重力场模型,通过重力异常揭示质量瘤和撞击盆地。星载或器载主/被动雷达设备还用于探测月壤和月球内部结构。在“嫦娥2号”任务中,实现了对拉格朗日平动点利萨如轨道飞行的测控,以及对图塔蒂斯小行星的飞掠探测。在“嫦娥3号”任务中,实现了多通道开环3向相位测距和多普勒测速技术。该月球无线电相位测距技术LRPR作为一种新的空间测量技术,可以用于测定台站的位置、潮汐、星体的自转特性。还可以与月球激光测距技术LLR融合,监测月球动力学运动变化,并有潜力用于未来的火星探测任务。
Planetary radio scientific exploration experiments were conducted in the “Chang’e 1/2/3” series of exploration missions, including: engineering and scientific measurement of the detector using astronomical VLBI technology, location observations, open-loop and closed-loop speed measurements Ranging observation, reconstructing and optimizing the lunar gravity field model based on microwave observations, and revealing mass and impact basins through gravity anomalies. Onboard or carrier-based / passive radar equipment is also used to detect lunar and lunar internal structures. In the “Chang’e 2” mission, it realized the measurement and control of the Läsar orbital flight of the Lagrange translation point, as well as the exploration of the Turtis asteroid. In the “Chang’e 3” mission, to achieve a multi-channel open-loop 3-phase ranging and Doppler velocimetry. The lunar radio phase ranging technology LRPR as a new space measurement technology can be used to determine the location of stations, tides, astral rotation characteristics. It can also be integrated with the Moon Laser Ranging LLR to monitor lunar kinetic changes and have potential for future Mars exploration missions.
