生物战剂/气溶胶激光雷达遥测技术研究

Study on LIDAR remote sensing technology for biological agent/aerosol

散射、荧光和偏振信息是生物战剂/气溶胶时空观测和识别的有效数据源。对Mie散射、紫外激光诱导荧光和偏振探测激光雷达的原理、数据反演等进行了阐述和讨论,并对消光系数、荧光和退偏振比的探测结果进行了探讨。实验和数据表明,消光系数、退偏振比和荧光的时空分布,用于生物战剂/气溶胶的探测和识别是可行的。

Scattering,fluorescence and polarization are the effective data sources for biological agent/aerosol time - space observation and identification. The theory and data inversion principles for Mie scattering,laser induced fluores- cence and polarization sensing LIDAR were stated and discussed. The sensing and data inversion results for extinction coefficient,fluorescence and horizontal linear depolarization ratio of biological agent/aerosol were also demonstra- ted. The results show that the three kinds of detecting technologies are reasonable and potential for biological agent/ aerosol detection and recognition.
