Abstract.
Radio methods are the
most simple and informative for remote studies of celestial bodies. Bistatic
sounding of the Moon is planned in the mission of "LUNA-RESURS". For
experiments radio device RLK-L will be installed on the orbiter
"LUNA-26". Bistatic sounding of the Moon is aimed at researching the
structure and dielectric properties of the upper layer of the Moon. The rocks
permittivity is connected with mineralogical composition of the grounds and
its structure depends on the history of formation. For bistatic measurements
RLK-L will use the frequency range from 175 MHz to 225 MHz. The thickness of
top cover of several meters is available for probing with radio waves of this
range. The device RLK-L will work together with the Irkutsk non-coherent
scattering radar of Institute of Solar Terrestrial Physics of Russian Academy
of Sciences. For preparing the experiment, predicting and interpreting the
results the 3-D model of the lunar surface will be used. In the article,
various types of selenographic coordinates are considered. The coordinate
system suitable for determining the center of a reflected spot is selected.
Formulas for determining coordinates of the center in the MOON ME coordinate
system are deduced.
Key words:
bistatic radar, coordinates, reflected spot, the Moon,
spacecraft.
