Low-Noise, High Dynamic Range Digital Receiver/Spectrometer for Radio Astronomy Applications

Abstract

In this paper, a recently developed digital receiver which satisfies to a large extent the modern requirements to such devices is presented. This receiver has been tested at the decameter radio telescope UTR-2. It is well known that the negative impact of radio frequency interference (RFI) on the quality of data is a matter of increasing concern especially for the low frequency radio astronomy.
