An antenna array of "n" individual parabolic dishes is arranged about a center in subarrays extending in North, East, South and West rows. Signals received by the antennas are combined into representations of the electromagnetic environment as viewed with various simultaneous beam geometries, through a combination of analog signal summation, and digital implementation of aperture synthesis techniques. All antennas monitor the same portion of sky. The array is able to scan the sky without physically moving the antennas. The angular resolution of the array greatly exceeds that of the individual antennas. A variety of different research objectives, such as targeted searches, all-sky surveys, sky mapping, interference studies, the study of a variety of natural astrophysical phenomena, and the search for intelligently generated microwave emissions of possible extraterrestrial origin, may be realized simultaneously.
