GlobeSAR mission is an international cooperation program

there are twelve countries participated in the program.GlobeSAR data are the first and sole airborne

dual-frequency and fully-polarized SAR data sets of covering the Chinese territory.This paper systematically presents the study results of GlobeSAR program in China.The radar backscatter intensity visualization model has been proposed to study the backscatter behaviors of various targets.Rice and euryale ferox received more attention than other targets

their backscatter behaviors in relation to frequency and polarization

and polarimetric features and responses are carefully studied.The geometric and radiometric correction

speckle noise filtering

image registration are applied to the multifrequency

multipolarization GlobeSAR data sets.The assessment of classification accuracy for maximum likelihood

neural net

and texture information added neural net classifiers shows that the texture information added neural net classifers achieved the highest accuracy.GlobeSAR images discriminated eleven land cover types

two forest types.Finally

the GlobeSAR data application results in agriculture

forest

geology

hydrology and tourism planning are introduced.
