Phase-based Radiometric System in Lunar Radio Measurements
Abstract
In December 2013, the Chang'E-3 lunar lander carrying an X-band beacon made a successful soft landing in the Rainbow Bay area, which fulfills a prerequisite for lunar radio measurement (LRM). A new LRM system had been built before the Chang'E-3 launch. And a stable phase transfer for multiple frequencies has been studied, and high-precision phase has been estimated for phase-based radiometric measurements. Finally, signal processing on the satellite DOR carrier has been conducted, and 10 mHz frequency estimation precision and 0.02 circle (7.2°) phase conjunction precision have been achieved.
