What does Lofar stand for?
LOFAR (Low Frequency Array) is currently the largest radio telescope operating at the lowest frequencies that can be observed from Earth. Unlike single-dish telescope, LOFAR is a multipurpose sensor network, with an innovative computer and network infrastructure that can handle extremely large data volumes.
When was Lofar built?
12 June 2010
LOFAR was officially opened on 12 June 2010 by Queen Beatrix of the Netherlands. Regular observations started in December 2012.
How many LOFAR stations are there?
Currently, LOFAR consists of 24 Core stations around Exloo, 14 Remote stations distributed over the Netherlands and 14 International stations distributed over Europe. Core stations consist of 48 HBA’s and 96 LBA’s and a total of 48 digital Receiver Units (RCU’s).
What is LOFAR in Sonar?
LOFAR is a typical method of passive sonar signal processing. It is based on the short-time Fourier transform (STFT) to obtain the time-frequency spectrum of the signal and uses the time accumulation of the low-frequency line spectrum to detect the line spectrum.
What type of telescope is the LOFAR telescope?
low frequency radio telescope
I-LOFAR is a low frequency radio telescope based at Birr Castle, Co.
What is demon analysis?
DEMON analysis is a narrowband analysis used for cavitation noise processing with further accumulation of data obtained from the controlled object.
What is Lofar in Sonar?
What is demon processing?
DEMON processing (DEtection of Modulation On Noise) is a technique employed by submariners to detect the presence of propeller craft. It uses the FFT of the envelope of band pass filtered sonar signals to emphasise the modulation in time of the pressure signal (see e.g. Coates 2001).
What is LOFAR-UK?
Welcome to the LOFAR-UK Website. The LOw Frequency ARray, LOFAR , is a radio telescope working at the lowest frequencies accessible from Earth. Combining many thousands of simple dipole receivers (just like the one in your radio at home) with the latest in high tech computing, LOFAR can survey wide areas…
How does LOFAR work?
Combining many thousands of simple dipole receivers (just like the one in your radio at home) with the latest in high tech computing, LOFAR can survey wide areas of the sky all at once and is opening up a new window for astronomers. LOFAR consists of many “stations” which are each composed of a large number of dipole receivers.
Where is the UK’s LOFAR station?
The UK’s LOFAR station, the Rawlings Array, is based at the Chilbolton Observatory in Hampshire. You can find more information about it on our Rawlings Array pages.
Where is the LOFAR array?
LOFAR consists of many “stations” which are each composed of a large number of dipole receivers. The majority of these are in the Netherlands, but there are also stations in Germany, France, the UK, Sweden and Poland. The UK’s LOFAR station, the Rawlings Array, is based at the Chilbolton Observatory in Hampshire.
