接着，基于C波段极化干涉数据，用ESPRIT算法估计植被冠层有效散射中心的相位；

Next, vegetation canopy scattering center phase is resolved by ESPRIT algorithm using C band Pol-InSAR data.

针对这种情况，从INSAR的基本原理入手，提出了一种新的利用平地干涉相位进行初始基线估计的方法。

So, this paper presented a new baseline estimation method based on the principle of INSAR, which used the phases of flat earth. Two types of data were used to do experiments.
