China has successfully opened its compound eyes, shooting the first ground-based radar three-dimensional lunar map in China.
CTOnews.com December 29 news, According to CCTV news report, Located in Chongqing City "China compound eye" Project Phase I project, Recently completed installation debugging and start-up observation work, Successfully shot the first domestic ground-based radar three-dimensional lunar map.
VDAR High Resolution Deep Space Active Observation Facility is also known as "Chinese Compound Eye." Large-scale distributed aperture radar is similar to many small antennas synthesized into a large antenna, although the power of a single radar is limited, but due to the power superposition between radar and radar, it can achieve ultra-long-range detection function.
CTOnews.com learned that unlike the Chinese Sky Eye, the Chinese compound eye can emit electromagnetic waves by itself and receive echoes to observe asteroids and terrestrial planets in the solar system.
According to previous information, the Chinese compound eye project is divided into three phases. The first phase is the "distributed radar astroimager verification test site," which will build four 16-meter radars to verify the technical feasibility and have the ability to observe the moon. The second phase is the "pre-research project of ultra-large distributed aperture radar high-resolution deep airspace active observation facilities," which will build 25 radars with a diameter of 20 meters to realize asteroid detection and imaging at a distance of 10 million kilometers. The third phase is for Beijing University of Technology to jointly apply for the national "Tenth Five-Year Plan" major scientific and technological infrastructure, and to build "ultra-large distributed aperture radar high-resolution deep airspace active observation facilities," including 400 20-meter radars, with an estimated detection distance of 150 million kilometers, with high-precision active observation capability of celestial bodies in the inner solar system.
