Abstract
It is necessary to implement online measurement of atmospheric density around spacecraft in order to better design aerodynamic appearance of hypersonic spacecraft and meet the demand of pneumatic identification. This is one of important problems that should be solved in domestic spacecraft design field but cannot be solved. In the paper, a technical solution of measuring atmospheric density by imaging lidar based on Rayleigh scattering principle is proposed aiming at flight characteristics of spacecraft and surrounding environment features during flight, atmospheric density online measuring instrument is developed, and difficulties and innovations in the development process are introduced. Calibration results indicate that precision of atmospheric density online measurement with the instrument can be controlled within 5%. Successful development of the instrument provides a new method for designing spacecraft appearance and improving aerodynamic identification.
