| 摘 要： | 针对InSAR中干涉相位条纹图的除噪滤波,提出了一种基于小波变换和加权圆周期中值算法的干涉纹图除噪方法,阐述了该方法的设计思想和具体算法实现步骤。实验结果证明该方法不仅有效地抑制了干涉纹图中的噪声,并且较好的保持了干涉纹图的相位信息。

| Abstract: | Aimed at the denoising ofinterferometric phase fringe, a interferogram denoising method of InSAS based on wavelet transform and periodic mean algorithm is proposed. Idea and procedure of the method are described in detail. Experiments have been carried out and the results show that the proposed method can reduce interferogram noise efficiently as well as preserve edge and detail very well. |
