Orbit Determination of Resident Space Objects Using the P-Band Mono-Beam Receiver of the Sardinia Radio Telescope

Applied Sciences, 2019
The population of space debris in near-Earth space is continuously growing and it represents a serious problem for active satellites and spacecraft. A performant ground-based and space-based network of sensors is necessary for space surveillance and ...

Dwingeloo – the golden radio telescope [PDF]

Astronomische Nachrichten, 2007
AbstractThe Dwingeloo 25‐m telesope, inaugurated in 1956, has played a major role in research for half a century. We trace its history back to its conception in 1944, and summarize its main achievements. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Response of the Effelsberg 100m radio telescope to signals in the near-field at 24 GHz [PDF]

Advances in Radio Science, 2003
Short range radar (SRR) for cars has been proposed to operate over 5 GHz of bandwidth at the 24 GHz ISM band. To estimate the level of interference from these devices on radio telescopes, the near-field antenna pattern has to be known.

CHIME FRB: An application of FFT beamforming for a radio telescope [PDF]

URSI General Assembly and Scientific Symposium, 2017
We have developed FFT beamforming techniques for the CHIME radio telescope, to search for and localize the astrophysical signals from Fast Radio Bursts (FRBs) over a large instantaneous field-of-view (FOV) while maintaining the full angular resolution of
