| Abstract: |
| In view of the needs of near space atmospheric environment detection, this paper introduced a kind of in situ detection technology for 30-100 km near space atmospheric density, wind field, temperature and air pressure—sounding rocket falling sphere detection technology. Detection principle, system composition and detection process were described. Detection data of the falling sphere was simulated successfully with the simulation method. Atmospheric products of 30-100 km near space density, wind field, temperature and air pressure were retrieved successfully with the simulation detection data. The technology has many advantages such as multiple parameters measurements, wide detection range, low load cost, relatively simple equipment, etc. It has great significance to the near space environment detection and environmental research in China. |
