Abstract Making use of bistatic SAR image simulation, polarimetric characteristics of BISAR image are studied. It is found that some conventional polarimetric parameters, such as Cloude’s , α,β,γ for interpretation of monostatic SAR image lose their effectiveness for bistatic case. A transform of the unified bistatic polar bases for BISAR image is presented, and the polarimetric parameters, i.e. α,β,γ, are redefined to preserve their merits of orientation independence. Image simulations show that the polarimetric characteristics of different terrain surfaces are well described using these unified bistatic polar bases, and newly redefined α,β,γ are also applicable to interpret different scattering mechanism. It provides a new way for bistatic image interpretation and information retrievals.
