📡 FAST Radio Telescope: Collecting Area & Signal Detection

Compare a small 25 m reference dish against the 500 m FAST telescope aimed at the same faint distant radio source: watch how collecting area sets the signal-to-noise ratio, turning the same signal into a noise-buried blip on the small dish and a confident detection spike on FAST.

⚙ Under the hood

Compare a small 25 m reference dish against the 500 m FAST telescope aimed at the same faint distant radio source: adjust the source's strength and distance and watch live spectrum/waterfall traces show the same signal as a noise-buried blip on the small dish but a confident detection spike on FAST, driven purely by collecting area.
