The ultra-wide distributed aperture radar high-resolution deep space active observation facility in Liangjiang New District, Chongqing, also known as the China Compound Eye, recently completed the installation, commissioning and start-up observation of the first phase of the project, and successfully captured the world's first distributed radar-based three-dimensional imaging of the lunar surface.
It is understood that ultra-large distributed aperture radar is similar to many small antennas combined into one large antenna. Although the power of a single radar is limited, it can achieve ultra-long-range detection functions due to the power superposition between radars. According to reports, unlike the Chinese Sky Eye, the Chinese Compound Eye can emit electromagnetic waves on its own and receive echoes 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 achieving high-resolution imaging observations of the moon, laying the foundation for the subsequent second and third phases of the project. After the completion of the third phase of the project, the detection range of the large-scale scientific device composed of hundreds of radars will reach 150 million kilometers, achieving my country's 50-year lead in the field of deep space detection radars.
