Abstract :
We have shown that area-averaged structure orientation angles relative to incident angle of POLSAR in urban area can be estimated from argument of correlation coefficient of circularly-polarized observation bases. It is quite interesting that by this approach we can estimate area-averaged urban parameters even if we can not distinguish them from conventional received signal component intensity map due to lack of spatial resolution.
