Mutual help in SETIs
Abstract
Techniques to establish communication between earth and extraterrestrial intelligent beings are examined analytically, emphasizing that the success of searches for extraterrestrial intelligence (SETIs) depends on the selection by both sender and receiver of one of a few mutually helpful SETI strategies. An equation for estimating the probability that an SETI will result in the recognition of an ETI signal is developed, and numerical results for various SETI strategies are presented in tables. A minimum approach employing 10 40-m 20-kW dish antennas for a 30-yr SETI in a 2500-light-year disk is proposed.
