Abstract

The optimal baseline of polarimetric interferometric synthetic aperture radar(POLinSAR)is analyzed based on the random volume over ground(RVoG)model in the application of estimating parameters of the volume scatterers.Based on the basic concepts of baseline decorrelation

RVoG model and phase tube

the existence of POLinSAR optimal baseline is proved.Then the definition of POLinSAR optimal baseline is given and the method for calculating its value is derived.The differences between InSAR optimal baseline and POLinSAR optimal baseline are also presented.Finally

by the experimental simulation

the optimal baseline is validated and the effects of various parameters on the choice of optimal baseline are discussed

which include radar system parameters

imaging geometry parameters and volume scatterer parameters.
