SAR产品图像像素定位方法的选择与参数优化

通过对几种合成孔雷达（ＳＡＲ）遥感图像的像元定位理论模型进行阐述了比较，得出距离－－多普勒（Ｒ－Ｄ）模型作为定位模型的核心内容为最佳。进而指出了定位模型建立和达到实用的过程中仍需完善和解决的若干问题，尤其是结合ＳＡＲ图像产品格式，指出了所需参数的获取与优化方法。

SELECTION AND OPTIMIZATION OF THE LOCATION METHOD FOR PIXELS IN SAR IMAGERY

By expatiating and comparing several theoretical models for pixel location of synthetic aperture radar(SAR) remote sensing imagery, we can conclude that the R D model is best as the core of location model. Several problems to be improved and accomplished are pointed out in the course of model building, and especially, the methods of acquisition and optimization of the parameters needed are also pionted out.
