Ask reporters 丨 What is the difference between "China Reunion Eyes" and "China Eyes"?

The reporter recently learned from the Chongqing Innovation Center of Beijing University of Science and Technology that Beijing University of Technology will take the lead in developing deep -space detection radar "China Reunion" in Chongqing. Some netizens asked through the Xinhua News Agency's "Ask Reporter" platform: What is "China Reunion"? Why is it called "China Reunion"? How is it different from "China Sky Eye"? Xinhua News Agency reporters answered the questions concerned by netizens.

Netizen: What is "Chinese Eyes"?

Reporter: "China Reunion Eye" is a deep -space detection radar planned by the Chongqing Innovation Center of Beijing Institute of Technology in Chongqing. Asteroid impacts such as defense and the situation of earth and moon situation.

Netizen: Why is it called "China Reunion"?

Reporter: "China Reunion Eye" is an image called. Everyone knows that compared with people's eyes, some insect eyes are composed of many small eyes, and "Chinese compound eye" is a large antenna composed of multiple small antennas, like the compound eye of insects.

Netizen: What is the difference between "China Reunion" and "China Eye"?

Reporter: In terms of configuration, "China Sky Eye" is a large 500 -meter -caliber, and "China Compound Eye" is a distributed radar, consisting of 25 to 36 small antennas, each antenna diameter of 25 meters, synthetic synthesis, synthesis A large antenna.

In terms of function, "China Sky Eye" is a radio -astronomical telescope, which mainly receives the signal emitted by the star body. It does not emit electromagnetic waves in itself. Essence Long Teng, president of Beijing University of Science and Technology, introduced, "Because the asteroid itself does not launch electromagnetic waves, it is invisible to use the radio astronomical telescope. You must actively launch an electromagnetic wave to see the asteroid."

Netizen: How far can "China Reunion" be seen?

Reporter: "China Compound Eye" is a deep -space detection radar with three -dimensional imaging/deformation monitoring. The expected distance of the project reaches 150 million kilometers. It is almost the average distance from the earth to the sun. Observe the near -ground/main asteroid, the moon, Venus, Mars, Jupiter and so on.

Netizen: What is the progress of the "China Reunion" project?

Reporter: According to reports, the first phase of the "China Eye Eye" project is "distributed radar celestial imaging measurement test field", and 4 16 -meter caliber radar is built to verify the feasibility of technology and have the ability to observe the moon. Installation and debugging in the Liangjiang New District of Chongqing.

The second phase of the project is "the pre -research project of the high -resolution deep airspace of high -resolution deep airspace of the large distributed aperture radar" and build 25 to 36 25 -meter -caliber radar to achieve a small planet detection and imaging of 10 million kilometers. The site selection has been completed in Yunyang County, Chongqing.

Netizen: Why does "China Reunion Eye" landed in Chongqing?

Reporter: Long Teng, president of Beijing Institute of Technology, said, "On the one hand, the project is based on the setting and observation of the geographical latitude of Chongqing based on the geographical latitude of Chongqing, and on the other hand, it is also based on the in -depth cooperation with Chongqing in scientific research."
