  • Abstract
    The Low Frequency Array (LOFAR) is the largest telescope in the world operating at a frequency range from 30 to 240 MHz. LOFAR is the first radio telescope of its size which uses phased array principles to detect radio signals. More than 10,000 antennas are installed in the field. The antennas are grouped in 44 stations. The maximal distance between the stations is about 1500 km resulting in a tremendous spatial resolution. In this paper the LOFAR system architecture is discussed and the status is described.
