"China Compound Eye": Active action beyond science fiction ｜ Yangtze Comment

The Chongqing Innovation Center of Beijing University of Science and Technology recently announced that a deep -space observation radar facility known as "China Reunion" is accelerating construction in Chongqing. The first phase of the project located in Liangjiang Longxing New City will complete the radar start detection in September. The second phase of the project will be completed. It has been determined to settle in Yunyang, Chongqing. The specialties of "China Reunion" are to shoot three -dimensional images for tens of millions of kilometers away to determine its threat to the earth.

This "China Reunion Eye" is a large radar composed of many small radar, which is the small asteroid detection part of the near -ground asteroid defense system established by China. Only by detecting and threatening evaluation of near -ground stars can we talk about defense. China plans to establish a near -earth asteroid defense system, which is publicly announced by the head of the National Aerospace Administration in April this year in CCTV in order to deal with the threat of the near -earth asteroid hitting the earth and contribute to the Chinese power to protect the earth and human security.

Seeing this, do you feel a bit of a sci -fi blockbuster? In 1999, the United States proposed a plan to establish a small asteroid defense system and had established some radar detection facilities. However, due to the lack of follow -up funding support, the plan was not available. According to the person in charge of the China National Space Administration, my country is striving for the end of the "Fourteenth Five -Year Plan" or in 2025 and 2026. Technical verification of planet track. This is not "science fiction", but it is effectively promoted.

The "China Eye Eye" project is one of the progress. According to China's plan, there are two sub -systems: foundation and heavenly foundation for asteroid detection. The formal name of the first phase is "distributed radar celestial image imaging measurement test field", which consists of 4 16 -meter pore diameter radar, which can achieve three -dimensional imaging of the moon; the second phase will build 25 high -resolution distributed radar The antenna diameter is 25 meters, which can achieve asteroid detection and imaging of 10 million kilometers away, and complete the demonstration verification of deep space radar detection and imaging; the third phase will detect small asteroids and celestial bodies of 150 million kilometers away.

In recent years, we often talk about the topic of "looking up at the starry sky", representing the Chinese people's ambitions to face the vast universe. In the face of the starry sky, it is actually more than just "looking up", observation, and detection, but also a problem that arrives or even develops. It is a field that must be "knowledge" and "line". "China Eye Eyes" and "China Reunion Eyes" all represent China's practical action in deep space exploration.

In terms of action, China has a series of major plans. For example, we have a "Tengyun Project" to find a reusable world flight round -trip tool. The "China Manned Men on the Monthly" plan released in 2013 will eventually realize the annihilation of the moon in the first 2030s, and the space station under construction is one of its staged results. The state has also approved a planet detection project. Tianwen No. 1 landing in Mars is the first step, and the marginal detection of the solar system will be performed.

To achieve the great rejuvenation of the Chinese nation, our journey is the sea of ​​stars. Near -ground asteroid defense systems, Chinese manned moon landing plans, and Chinese planet detection projects show the actions of Chinese people's knowledge and action. "Chinese Eye Eyes", "Chinese Eyes", Space Station ... Every step is not to selfish selfishness, but to focus on the community of human destiny, each step is down -to -earth.
