High-Sensitivity Phased Arrays for Radio Astronomy and Satellite Communications

High-Sensitivity Phased Arrays for Radio Astronomy and Satellite Communications

Radio astronomy is used to study stars, galaxies, black holes and gas clouds radiation at radio frequencies. Detecting extremely weak signals from deep space radio sources requires high sensitive feed system associated with large dish antennas. The key figure of merit is survey speed, or the time re...
