Opening a New Window on the Universe: High-Resolution, Long-Wavelength Radio Astronomy

Abstract : Although Jansky's (1933) discovery of radio astronomy was at decametric wavelengths, the urgent quest for ever higher angular resolution and the fact that ionospheric structure limits interferometric imaging to short (less than 5 km) baselines at long wavelengths (LW, taken to be 20 m or 15 to 150 MHz) has left the LW region among the most poorly explored in the entire spectrum.
