| 説明 | Another method of linking up radio telescopes is through a technique called beamforming. In beamforming, dishes are not paired up (as they are in interferometry) but rather are all linked together to synthesize a single large telescope - also referred to as a beam. The larger the size of the array, the smaller the beam can become. Beamforming is of particular interest to SETI researchers as it allows them to focus in on the radio waves coming in from only a very small portion of the sky (such as those emanating from a single star in the sky). Beamforming is also of interest to other researchers, such as those interested in masers or pulsars (the highly magnetized remains of massive stars and stellar explosions.)Source Allen Telescope Arraylt 026 |
