PROJECT TITLE :

Capability of Rice Mapping Using Hybrid Polarimetric SAR Data

ABSTRACT:

The objectives of this paper are to investigate the capability of hybrid polarimetric synthetic aperture radar (SAR) information for rice mapping and to explore the relationships between the hybrid polarimetric info and rice biophysical parameters. The linear polarization ratio (μL) is analyzed on the premise of reflection symmetry and simulated data, and has been demonstrated to behave equally to the HH/VV polarization ratio, which has been widely utilized in rice and wheat mapping. The degree of linear polarization (PL) shows nice potential in rice monitoring likewise. Additionally, a modified entropy-alpha decomposition method for hybrid polarimetric SAR is proposed to research the temporal scattering behaviors of rice in several growth stages. The degree of polarization (m), μL and PL are shown to be ready to replicate the growth status of rice to a sure extent, and their empirical models are explored. Time-series pictures acquired by Radarsat-2 at C-band and in situ data, like the recent biomass, dry biomass, height, and days once transplantation (DAT), are used to demonstrate the analytical method and therefore the foresaid conclusions.
