An Analysis of the Elements of an All Sky Survey

One component of the NASA search for microwave signals of extraterrestrial intelligent origin will be an all sky survey at a significantly low limiting flux over a broad frequency range. We are currently designing an overall strategy which will permit this survey to be: (1) carried out using existing antennas in less than 3 years of observation time, (2) uniform in sensitivity (within 0.5 db) over the celestial sphere for any given frequency, and (3) complete to 6×10-23 W/m2 or better over the frequency range 1.2GHz≤;ν≤10GHz with a frequency resolution of 32 Hz.
