Since 2017, the Institute of Applied Astronomy of the Russian Academy of Sciences in cooperation with the National Astronomical Observatories of the Chinese Academy of Sciences has been conducting observations of the Chang’E-3 lander carrier wave signal. The paper presents the features of observation scheduling and results of data processing. High-precision phase radar measurements have been obtained with an instrumental error of 1–2 mm. The deviation of residuals in model calculations does not exceed ± 1 cm. The estimates of CE-3 lander position have been obtained with an accuracy of 0.5’’, 7.4 m and 3.2 m in celenocentric cylindrical longitude, Px and Py coordinates, respectively.

“…The dashed line shows the distances to the Earth and the NEAs diameters assuming a Signal-to-Noise Ratio of 3, a rotation period P = 9 h, a radar albedoσ = 0.1 and a transmitter power P tx = 400 kW on a corresponding round-trip light-times. We can consider the obtained curve as a lower limit of the RT-32 sensitivity in bistatic radar observations of NEAs [1].…”

“…Since 2015, the Institute of Applied Astronomy (IAA) of the Russian Academy of Sciences and the Goldstone Deep Space Communications Complex have regularly conducted intercontinental radar observations of Near Earth Objects (NEOs) using the DSS-14 antenna as a transmitter and the RT-32 radio telescopes as receivers, thus performing a "bi-static" mode of radar observation [14][15][16][17][18][19][20].…”

Earth-based radar astronomical observations provide information on surface characteristics, orbits, and rotations for a wide variety of solar system objects. Based on compound radio telescopes, both the Chinese VLBI (Very Long Baseline Interferometry) network (CVN) and the Russian VLBI network (Quasar), in cooperation with the Chinese radar transmitters, we present the current ground radar astronomical observations of the moon. The spectrum of the reflected radio signals was obtained and the Doppler frequency shift in bi-static radar mode was measured. Radar albedo of the observed region and power ratios of the reflected signals with left- and right-hand circular polarizations were determined, allowing us to study the radar reflectivity and near-surface wavelength-scale roughness of the moon. Future developments on radar astronomy are also discussed in the paper.
