Recent advances in calibration and imaging algorithms at low radio frequencies, combined with advances in digital signal processing, have led to the realization that a large low-frequency radio array is now technically feasible and affordable. Improvements of one to two orders of magnitude (depending on frequency) in both sensitivity and resolution would make possible new approaches to the study of many astrophysics problems. In particular, key science areas that would be revolutionized by such an array are the high redshift universe, the epoch of reionization, the distribution of galactic cosmic rays, the bursting and transient universe, ionospheric structure, and the solar-terrestrial relationship. An ASTRON-NRL-MIT collaboration has proposed the design and construction of a low frequency array (LOFAR) made up of over 13,000 fixed dipole and dipole-array antennas that would operate in the 15-240 MHz range. The goals are to achieve a collecting area of one square kilometer at 15 MHz, arc-second angular resolution, high dynamic range, and wide-field imaging capabilities.
