Abstract

Atmospheric transmittance is a key parameter in infrared measurement calibration. The transmittance of the corresponding band is usually obtained based on theoretical calculation. The air based active radiation source was mounted below the airship, and the air transmittance measurement verification test based on the air based active radiation source was carried out. The air transmittance correction could be completed to improve the accuracy of the air transmittance. A space-based active radiation source with a hemispherical shape of 400mm in diameter and a maximum weight of 130kg is designed in this paper. The radiation source temperature range can reach normal temperature to 600℃. The ground verification shows that when the actual temperature of the space-based active radiation source is higher than 155℃, the radiation brightness stability is better than ±2%, and the temperature uniformity is better than ±5℃.
