This is called the baseline.
Increasing the distance between the two most widely separated radio telescopes has an enormous effect on resolution.
Placing two small radio telescopes 100 meters apart allows for interferometry, which enhances the overall resolution of the observations. This configuration effectively simulates a larger telescope with a diameter equal to the distance between the two dishes, enabling the detection of finer details in astronomical objects. Additionally, combining data from both telescopes improves sensitivity and signal quality, allowing for more accurate measurements of celestial phenomena.
Radiation other than light and radio waves hardly penetrates Earth's atmosphere.
# Cosmic background radiation (remnants of the Big Bang). # Quasars.
Radio telescopes are generally much larger than optical telescopes for two reasons: First, the amount of radio radiation reaching Earth from space is tiny compared with optical wavelengths, so a large collecting area is essential. Second, the long wavelengths of radio waves mean that diffraction severely limits the resolution unless large instruments are used.

Two or more radio telescopes!
Astronomers improved radio images by connecting telescopes. If two radio telescopes are separated by distance but are connected electronically, their signals can be combined using a computer. The resulting images are as good as if one telescope were used that was as big as the distance between the two. This method is called interferometry.

The distance between the two antennae that are the farthest apart is the baseline of a radio telescope array..

Radio waves are used to help transmit signals between two devices.Some devices which use radio waves are:RadiosTelevisionsMobile (cell) phonesCordless telephonesNavigational devices (such as GPS and satellite tracking)RadarRadio-tuned clocks and watchesRadio telescopes
Radio telescopes can detect radio waves from celestial objects billions of light-years away, allowing scientists to observe phenomena such as quasars, pulsars, and the cosmic microwave background radiation. The distance at which a radio telescope can "see" depends on the strength of the signal emitted by the object being observed and the sensitivity of the telescope's receivers.
The Citizens Band radio is defined to be a short distance radio communications device. Its uses includes cheap and efficient talking between two stations without any interruptions.
lengthThe distance between two points is called the displacement.
