China has started construction on an early warning radar station. It is so far away it is difficult to imagine. The complex will be capable of detecting objects at 150 million kilometers. This is the distance the Sun is from the Earth.
China Fuyan, a complex known as the compound eye, is located in Chongqing. It’s designed to detect asteroids that are close to Earth. However, it can also see objects closer to Earth such as the Moon and artificial satellites.
It will include more than 20 antennas distributed with a diameter between 25-30 meters. The project is being led by the Beijing Institute of Technology.
Two radars, which will launch in September 2022, will be constructed at the initial stage. Their number will then rise to four. This will give a three-dimensional view of the moon. More than 20 “dishes”, which will give a detailed, three-dimensional view of all objects within the Earth’s orbit, and the inner parts of the solar system, will be constructed after that. Scientists are not yet able to determine the exact timing for the final stage.
