Ultranarrowband searches for extraterrestrial intelligence with dedicated signal-processing hardware
Abstract
An evaluation is made of the prospects for SETI applications of multichannel spectroscopy, assuming narrowband RF beacon transmission, with a mHz resolution that matches interstellar medium properties. Receiver Doppler corrections must furnish substantial interference rejection. Results are presented from an Arecibo antenna search of 250 sunlike stars at 1.4 and 2.8 GHz. A meridian transit search of the northern sky is also in progress with the Harvard-Smithsonian 26-m antenna.
