The Earth Observation Technology Application Research Department has successfully acquired two projects of the National Natural Science Foundation of China in 2011 TEXT SIZE: A A A

 

As having acquired several projects of the National Natural Science Foundation of China continuously in the last 3 years, the Earth Observation Technology Application Research Department has successfully acquired two projects of the National Natural Science Foundation of China in 2011.Up to the present, the Earth Observation Technology Application Research Department has successfully acquired totally eight projects of the National Natural Science Foundation of China independently.

The two acquired projects of the National Natural Science Foundation of China in 2011 include “Investigation on the forest height inversion methods based on UAV Pol-InSAR” applied by Dr. Yongsheng Zhou and “Retrieval of Land Surface Temperature/Emissivity and Atmospheric Correction from High Time-series Thermal Infrared Data” applied by Dr. Yonggang Qian.

Aiming at the poor penetrability of high-frequency radar wave in forests, The project of “Investigation on the forest height inversion methods based on UAV Pol-InSAR”  studies the forest’s height inversion method of high-frequency Pol-InSAR; as the forest’s height inversion is vulnerable to the terrain slope, it studies the forest’s height inversion method of Pol-InSAR in undulating terrain region. On the basis mentioned above, the project tries to set up a performance analysis model with parameters include coherency, Phase center separation ability and forest’s height inversion precision, analyze the influence of system parameters and lay a foundation for improving the performance of forest’s height inversion.

The project of “Retrieval of Land Surface Temperature/Emissivity and Atmospheric Correction from High Time-series Thermal Infrared Data” utilizes the infrared data of Fengyun Stationary meteorological satellite together with the atmospheric profile data at several moments in a day to explore the pattern of diurnal temperature variation and present a new atmospheric correction method of Stationary meteorological satellite’s time series infrared data. The study sets up a new surface emissivity inversion model of middle/thermal infrared channel by utilizing atmospheric corrected time series middle/thermal infrared data at moments only in the daytime, and develops the inversion method of earth surface temperature supported by the surface emissivity data. The study can provide technical support to the remote sensing application of China’s Fengyun series stationary satellites and has a very important theoretical and application value.
