Parkes RFI Environment and Mitigation
نویسندگان
چکیده
An obvious issue with a low-frequency broad-band receiver is the degree to which the science data are affected by radio-frequency interference (RFI). RFI comes in two main classes: a) relatively narrow-band quasi-steady transmissions and b) broad-band transient signals. Very strong narrowband signals can result in non-linear responses which dramatically spread the signal in frequency. Transient emissions are a particular problem for pulsar observations since observing systems have high time resolution.

RFI Mitigation for Pulsar Observations
An adaptive filter for RFI mitigation has been brought on-line at the Parkes observatory, embedded in the most recent pulsar observing system. The filter meets the design criteria, and provides substantial RFI mitigation. This note describes the filter and some recent field trials.
متن کاملRFI mitigation methods in radio astronomy
Various methods of radio frequency interference (RFI) mitigation methods at radio astronomy telescopes are being considered. Special attention is given to real-time processing algorithms. Computer simulations and observational results are used to describe the applicability of these methods. Best results can be achieved when the RFI mitigation procedures are adapted to the particular radio teles...
متن کاملExamination of a simple pulse blanking technique for RFI mitigation
Spectroscopy at L-band can be adversely impacted by radio frequency interference (RFI) due to the presence of numerous sources, especially pulsed RFI from radars operating below 1400 MHz. RFI mitigation is very important to deal with this problem. A simple strategy for reducing pulsed RFI termed “asynchronous pulse blanking” has been implemented in a digital receiver developed at The Ohio State...

متن کاملRFI subtraction from time-averaged spectroscopy using a reference horn and cross power spectra
Effective radio frequency interference (RFI) cancellation for spectroscopic applications can take place using time averaged spectra. An RFI “reference signal,” constructed from the cross power spectrum of the signals from the two polarizations of a reference horn pointed at the source of the RFI signal, in combination with cross power spectra with the signals from the Parkes telescope, allows c...
