| 英文摘要 | The radar research of space debris objects at HEO and GEO are carried out using Evpatoria RT-70 transmitter and Low Frequency VLBI Network since 2001. Primary goal of these experiments is developing and validation of the VLBI radar method to obtain the information on trajectory parameters, attitude motion and shape for known objects. The echoes from about 50 objects were recorded on magnetic tapes or PC-disks at Bear Lakes RT-64, Noto RT-32, Urumqi RT-25 and Simeiz RT-22. The correlation processing in N. Novgorod and Noto provided measuring the Doppler shifts, angular coordinates, rotation periods and dimensions for most of studied objects. Pulkovo Cooperation of Optical Observers (PulCOO) and other optical facilities carried out positional measurements in support of radar experiments. The second goal was adjusting of so called the beam-park (fixed beam direction with respect to the rotated Earth) and beam-track (fixed beam direction with respect to the inertial frame) methods to search of uncatalogued fragments. The partial processing of beam-track experiment of July 2004 allowed to clearly detect the echoes from five catalogued GEO objects and measure the moment of signal maximum, duration of beam crossing and Doppler shift. |
