摘要：Radar remote sensing technology has become an important method for stable and long-time rice monitoring for its capability to operate in all weather conditions. In this paper, ENVISAT Advanced Synthetic Aperture Radar (ASAR) alternative polarization VV/HH data was used for rice monitoring in Xinghua rice experiment site in the middle of Jiangsu Province. Firstly, a threshold classification method was developed for mapping rice growth area, according to the different characteristic of backscatter coefficients between paddy rice and other land surface objects. Then, relational models were built for retrieving rice growth parameters from ASAR image, based on correlation analysis between backscatter coefficients and field measurements. Meanwhile an optical multi-spectral image was used as ancillary data for rice parameters retrieval. As expected, the retrieved rice growth parameters were consistent with those of field measurements.
