SIGNAL-TO-NOISE: Embroidered Cap

Signal to noise is a quantity utilized not only by radio astronomers, but also many branches of astronomy, signal processing, ham radio, and other fields of technology.



The principle measurement is the power of the signal being received divided by the power of the background noise. The longer an astronomer points their telescope at a celestial object, the more signal they will collect. Meanwhile the noise, with its random nature, gradually nullifies itself during a long integration.



This allows the patient among us to draw insights from the background chaos.
Help us to help fledgling radio astronomy projects around the world by purchasing some radio astronomy apparel.
