Inexpensive Interferometer for Low Frequency Radio Astronomy
LOFAR is a next-generation radio telescope under construction in the Netherlands with long-baseline stations under development in other European countries. LOFAR is an emerging European sensor network with continental dimensions for space and Earth observations. The LOFAR telescope uses phased antenna arrays to form an aperture synthesis telescope for receiving radio signals in the frequency band of 30 - 240 MHz. There are currently discussions with research institutions from Germany, UK, Italy, France, Poland and Sweden, aiming the installation of LOFAR stations in these countries. These partnerships will extend the "Wide area sensor network" and the resolution and sensitivity of the LOFAR system in Europe.
