Аннотация: Six VLBI radar experiments on the research of Earth group planets, near-Earth asteroids and space debris objects were performed during 1999-2003 with the help of the Evpatoria RT-70 planetary radar (Ukraine) and with the participation of the receiving antennas Bear Lakes RT-64 (Russia), Noto RT-32 (Italy), Torun RT-32 (Poland), Shanghai RT-25 (China), Urumqi RT-25 (China), Simeiz RT-22 (Ukraine) et al. Combination of radar and VLBI methods allowed us to obtain a new scientific instrument for the measurements of short-periodic variations of planet proper rotations and for the determination of solar system body orbits in the Radio Reference Frame. Echo-signals from 25 space debris objects at geostationary, high-elliptical and half-day orbits as well as from Venus and Mars were detected. Precise Doppler shift, main period of rotation and size estimations were derived for some objects.
