“…The counterpart of the BIRALES system is the BIRALET, which employs a different receiving segment, represented by the Sardinia Radio Telescope (SRT). The SRT is a 64 m dish fully steerable wheel-and-track parabolic antenna, able to operate in the frequency range 0.3-116 GHz [47,48], located 35 km north of Cagliari (Sardinia, Italy). Its azimuth and elevation maximum rotation speeds, 0.85 • /s and 0.5 • /s, respectively, allow for potential debris tracking.…”

Space debris monitoring is nowadays a priority for worldwide space agencies, due to the serious threat that these objects present. More and more efforts have been made to extend the network of available radar systems devoted to the control of space. A meticulous review has been done in this paper, in order to find and classify the considerable amounts of data provided by the scientific community that deal with RADAR measurement for the debris monitoring and tracking. The information gathered is organized based on the volume of found data and classified taking into account the geographical location of the facilities.

“…The two main radar systems for space debris monitoring in Italy are the BIRALES (Bistatic Radar for Low Earth Orbit Survey) [8] and the BIRALET (Bistatic Radar for Low Earth Orbit Tracking) [9] (refer to the Supplementary Materials). These bistatic radars share the same transmitter, but, for the first system, the receiver is the Northern Cross, located in Medicina, near Bologna (Northern Italy), whereas for the second one, the receiver is the Sardinia Radio Telescope (SRT), located near Cagliari (Sardinia, South-West Italy) [9,10]. Starting from early 2014 [11], the SRT has been involved 2 of 10 in the Italian and European space debris monitoring program and it has been gradually upgraded to make it more suitable for space debris observations [12].…”

Space debris is internationally recognized as a planetary threat. Efforts to enhance the worldwide radar monitoring networks have been intensified in the last years. Among the new radars employed for the observations, one of the most promising is the Bistatic Radar for Low Earth Orbit (LEO) Tracking (BIRALET), which employs the Sardinia Radio Telescope as a receiving segment. The Sardinia Radio Telescope (SRT) has recently been proven to be a reliable instrument for space debris monitoring and, for this purpose, over the years has undergone some substantial modifications in order to be able to rise to the status of a fully functional radar receiver. However, an extensive measurement campaign, in order to assess the real potential of the radar, has never been done before. In this paper, the authors present the first real space debris measurement campaign of the SRT, made between December 2018 and October 2019 using the new dedicated channel of the P-band receiver. A total of 27 objects were correctly detected during this campaign, characterized by a radar cross section (RCS) interval between 0.13 and 13.4 m2 and a range interval between 459 and 1224 km.
