Space Debris Detection by Space Borne Radar in the Low Earth Orbit

The article focuses on the detection of the 'dangerous space debris' with diameter from 5 mm to 7 cm.The small,high-speed debris around the low earth orbit are damage to the satellites and the spacecrafts.By analyzing the critical technologies about space borne detection of the dangerous space debris the article put forward a millimeter wave phased-array radar system and the 35 GHz radar system is designed.
