Implementation of LOFAR RFI mitigation strategy
نویسندگان
چکیده
ASTRON is building the world’s largest radio telescope for low frequencies, LOFAR. LOFAR is optimized for detecting astronomical signals in the 30-80 MHz and 120-240 MHz frequency windows. Since this part of the spectrum is in extensive use by others, a special RFI mitigation strategy is implemented which will be described in the paper. International RFI measurements will be presented and we will focus on practical implementation issues such as the impact of Digital Video Broadcast, RF emissions from power lines and the influence of large wind turbines on the EM environment.

Exascale Real-Time Radio Frequency Interference Mitigation
Radio Frequency Interference (RFI) mitigation is extremely important to take advantage of the vastly improved bandwidth, sensitivity, and field-of-view of exascale telescopes. For current instruments, RFI mitigation is typically done offline, and in some cases (partially) manually. At the same time, it is clear that due to the high bandwidth requirements, RFI mitigation will have to be done aut...
متن کاملAssessment of RFI measurements for LOFAR
In the North-Western part of Europe, ASTRON is building the world-largest largest low-frequency radio telescope. The telescope is based on phased array principles and is known as the LOw Frequency ARray (LOFAR). LOFAR is optimized for detecting astronomical signals in the 30-80 MHz and 120-240 MHz frequency windows. Since this part of the spectrum is in extensive use by others, special care mus...
متن کاملThe Dynamic Spectrum of Interplanetary Scintillation: First Solar Wind Observations on LOFAR
The LOw Frequency ARray (LOFAR) is a next-generation radio telescope which uses thousands of stationary dipoles to observe celestial phenomena. These dipoles are grouped in various ‘stations’ which are centred on the Netherlands with additional ‘stations’ across Europe. The telescope is designed to operate at frequencies from 10 to 240MHz with very large fractional bandwidths (25-100%). Several...
متن کاملCyclostationary approaches for spatial RFI mitigation in radio astronomy
Radio astronomical observations are increasingly corrupted by radio frequency interferences (RFIs), and real time filtering algorithms are becoming essential. In this paper, it is shown how spatial processing techniques can limit the impact of the incoming RFIs for phased array radio telescopes. The proposed approaches are based on estimation of the RFI spatial signature. It requires the diagon...
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...
