The filtered results to a real interferogram showed the proposed method is powerful to interferogram speckle noise reduction , as well as it can preserve fine details in the interferogram that are directly related to the ground topography and maintain phase values distribution
对一幅干涉相位图的滤波结果表明，该算法很好的抑制了斑点噪声，极大的降低了残余点的数量，保持了条纹边缘和相位细节信息，并使绝对相位保持在一定的动态范围。
