Abstract

The Institute of Applied Astronomy of the Russian Academy of Sciences regularly conduct radar observations of near-Earth objects (NEO) using 32-m radio telescopes (RT-32) of “Quasar” VLBI network. Planetary locators of the Goldstone Deep Space Communications Complex (USA) and the National Astronomical Observatories (PRC) are signal transmitters. To carry out such observations, the special software for radar observation scheduling and echo signal data processing has been developed. Joint observation windows, Doppler frequency shift of the recorded signal and signal-to-noise ratio are determined for a given configuration of the transmitting and receiving antenna systems and selected NEO during the radar observations scheduling. The processing of radar observations is performed taking into account the calculated ephemeris and protocol files of the radio telescope control system. As a result, the continuous wave echo power spectra of the recorded echo signals were obtained and their analysis was carried out.

regularly conduct radar observations of near-Earth objects (NEO)
using 32-m radio telescopes (RT-32) of “Quasar” VLBI network.
Planetary locators of the Goldstone Deep Space Communications Complex
(USA) and the National Astronomical Observatories (PRC) are signal
transmitters. To carry out such observations, the special software
for radar observation scheduling and echo signal data processing has
been developed. Joint observation windows, Doppler frequency shift of
the recorded signal and signal-to-noise ratio are determined for a
given configuration of the transmitting and receiving antenna systems
and selected NEO during the radar observations scheduling. The
processing of radar observations is performed taking into account the
calculated ephemeris and protocol files of the radio telescope
control system. As a result, the continuous wave echo power spectra
of the recorded echo signals were obtained and their analysis was
carried out.
