The ultra-large distributed aperture radar high-resolution deep space active observation facility located in Liangjiang New District, Chongqing, also known as China Compound Eye, has recently completed the installation, commissioning and start-up observation of the first phase of the project, and successfully captured the world's first three-dimensional imaging based on distributed radar. Moon map.

It is understood that the ultra-large distributed aperture radar is similar to the synthesis of many small antennas into one large antenna. Although the power of a single radar is limited, due to the power superposition between the radar and the radar, it can realize the ultra-long-range detection function. According to reports, unlike the Chinese Sky Eye, the Chinese Compound Eye can emit electromagnetic waves by itself and receive echoes, so as to observe asteroids and terrestrial planets in the solar system.

The China Compound Eye Project is led by the Chongqing Innovation Center of Beijing Institute of Technology. The first phase of the project verified the distributed working mode of the large system by realizing high-resolution imaging observations of the moon, laying the foundation for the subsequent second and third phases of the project. It is planned that after the completion of the third phase of the project, the detection distance of the large scientific device composed of hundreds of radars can reach 150 million kilometers, realizing my country's 50-year leading edge in the field of deep space detection radar.
