Practical Limits in the Sensitivity-Linearity Trade-off for Radio Telescope Front Ends in the HF and VHF-low Bands [PDF]

, 2016
Radio telescope front ends must have simultaneously low noise and sufficiently-high linearity to accommodate interfering signals. Typically these are opposing design goals. For modern radio telescopes operating in the HF (3-30 MHz) and VHF-low (30-88 MHz)

Probing ionospheric structures using the LOFAR radio telescope [PDF]

, 2016
LOFAR is the LOw‐Frequency Radio interferometer ARray located at midlatitude (52°53′N). Here we present results on ionospheric structures derived from 29 LOFAR nighttime observations during the winters of 2012/2013 and 2013/2014.

The Sardinia Radio Telescope

, 2018
In this talk, I will review the current status of the Sardinia Radio Telescope and the near-future technical developments. In particular, I will discuss the new generation receivers and focus on the spectroscopic capabilities of the telescope and on the impact that the SRT could have in the field of star formation .
