Issue Date: | 2019 | Volume: | 2019 IEEE 2nd Ukraine Conference on Electrical and Computer Engineering (UKRCON) | First Page: | 133-136 | Abstract: | The population of space debris is continuously growing and it represents a potential problem for satellites and spacecraft. In fact, new collisions could exponentially rise the number of debris and so the level of threat represented by these objects. To prevent new collisions, the monitoring of space environment is necessary. For this reason, radar measurements are relevant, in particular to observe Space Debris in Low Earth Orbit. In recent years, the Sardinia Radio Telescope, a fully steerable wheel-and-track 64-m antenna, located in Sardinia (Italy), has been used as a receiver in a Pband bi-static radar for space debris monitoring purposes. In this paper the authors investigate the advantages of using a Phased Array Feed in C-band for space debris monitoring (e.g. improved sensitivity and gain, detection of the object trajectory allowed by multiple beams, improvement of the orbit determination of known and unknown debris), as a receiver of the Sardinia Radio Telescope compared to the already used mono-beam P-band receiver. | Conference Name: | 2019 IEEE 2nd Ukraine Conference on Electrical and Computer Engineering (UKRCON) | Conference Place: | Lviv, Ukraine | Conference Date: | 02-06 July, 2019 | URI: | http://hdl.handle.net/20.500.12386/34767 | URL: | http://www.scopus.com/inward/record.url?eid=2-s2.0-85073300200&partnerID=MN8TOARS https://ieeexplore.ieee.org/document/8879919 |
