The Frequency Agile Solar Radiotelescope (FASR) is a radio interferometer designed to make high spatial resolution images of the Sun across a broad range of radio wavelengths simultaneously, allowing the technique of imaging spectroscopy to be exploited on a routine basis. The telescope will cover the frequency range 0.1-30 GHz using several sets of receiving elements that provide full-disk imaging, with of order 100 antennas at highest frequency range. FASR will be optimized for solar radio phenomena and will be the most powerful and versatile radioheliograph ever built, providing an improvement of orders of magnitude in image quality over existing instruments. FASR recently received the top ranking amongst all small projects considered by the decadal survey of the National Academy of Science Committee on Solar and Space Physics. FASR will probe all phenomena in the solar atmosphere from the mid-chromosphere outwards. In particular, FASR will provide direct measurement of coronal magnetic field strengths, will image the nonthermal solar atmosphere and show directly the locations of electrons accelerated by solar flares, will provide images of coronal mass ejections travelling outwwards through the solar corona, and supply extensive data products for forecasting and synoptic studies. A major emphasis in the project is to make FASR data as widely and easily used as possible, i.e., providing the general user with processed, fully-calibrated high-quality images that do not need particular knowledge of radio astronomy for interpretation. This paper will describe the telescope and its science goals, and summarize its current status.
