A large array of antennae has been built at the Radioastronomy Observatory, Nancay, France, to study solar and planetary decametric emissions. This array has a high gain (25 db) in a broad range of frequencies and is steerable through a large part of the sky. We present the main characteristics of this array, and the receives which are used to show the importance of the equipment for Jovian studies. We summarize the results already obtained and describe some topics which are presently being studied. |
