Detecting space debris with lidar

DONG Ji-hui; HU Qi-quan

Based on the characteristic of space circumstance and space debris,the lidar equation in the space is deduced,and the space radiation is analyzed at length.The formula of the minimal detectable laser power is deduced in detail,and the minimal emitting laser power and the signal-to-noise ratio of the system are given where-after.The results indicate that the large space debris within dozens of kilometers can be detected with lidar.
