According to the Range Doppler equations, the geometric calibration of SAR image can be realized using SAR imaging parameters.
依据合成孔径雷达(SAR)距离方程和多普勒方程,用SAR成像参数可实现SAR图像的几何校正。

First, we regularize the attraction force field in the geometric active contour model to extend the capture range of the object boundaries, and improve the ability of convergence to the concavities.
