| 摘 要： | 本论文以相位差平均波动函数法为基础,提出了多视波动配准方法。该方法首先对配准图像对进行多视平均处理,再对多视处理后的干涉图求取相位差平均波动函数值。该配准方法抑制了配准过程中的多峰现象,在精度和运算量上都有一定的改进,且没有继承多视处理降低二维分辨率的缺点。实际湖试数据验证了该方法的效果。后续处理得到的干涉图条纹清晰,并与实际地形吻合。

| Abstract: | Based on average fluctuations function of phase difference images, a registration
method of multilooking images is proposed in this paper. In this method, multilooking average
processing is performed to the two images to be registrated, then average fluctuation functions
of the phase difference are calculated acoording to interference patterns. It restrains the
multi-peak phenomenon, improves both precision and efficiency, and it doesn't inherit the
resolution fall from multilook processing. Its ability is proven by results from INSAS lake-trial.
