A New Method of Coherence Optimization Based on the Phase and Coherence Magnitude in Polarimetric SAR Interferometry

LONG Jiangping;LIU Feng;DUAN Zhugeng;College of Science,Central South University of Forestry and Technology;  
The complex coherence of polarimetric synthetic aperture radar interferometry(PolInSAR)includes the magnitude and phase.The magnitude of coherence is used to measure the quality of the interference phase,and phase center represents the position of the scattering.So,how to improve the accuracy of the coherence magnitude and phase is very important for the forest parameters inversion.Maximum difference of the coherence magnitude or maximum separation of the phase,based on the coherence region,is considered partial information of the complex coherence.In this paper,a new method of coherence optimization,combined with the coherence magnitude and phase information,is established with relational degree.Applied the new approach to estimate the optimal coherence,the optimal polarimetric state of the scattering can be obtained to estimate the optimization coherence.Experimental results show that the optimal coherence criterion,jointed coherence magnitude and phase,can effectively distinguish the phase center of surface scattering and the forest canopy,and improve the reliability of the forest height inversion.
