Abstract
The Italian National Institute for Astrophysics (INAF) has been involved in the European EU-SST (European Space Surveillance and Tracking - https://www.eusst.eu/) program for the monitoring of space debris, since its constitution. INAF builds and manages optical and radio telescopes which can be used to observe not only celestial sources but also space objects. One of the radio sensors used in EU-SST by INAF is the BIRALET (Bi-Static Radar for Leo Tracking) system, which is based on the 64 meters Sardinia Radio Telescope (http://www.srt.inaf.it/) used as a receiver antenna and on a 7-meters antenna used as a transmitter. The seminar will illustrate the problem of space debris for the development of the Space Economy, the functioning of the EU-SST monitoring system and a description of the BIRALET system and of the results it produced.
