InWF : Filtered Wrapped Interferogram

Product Description

This product corresponds to the filtered wrapped interferogram.

The geotiff file has 2 bands:

• band 1 is the filtered wrapped phase (phase difference between the two acquisitions) of the interferogram

• band 2 is the product of the two image’s amplitudes.

The png file has 1 band:

• band 1 is the filtered wrapped phase of the interferogram, normalized by a color palette.

Available products

The InWF produts are available in one resolution:

• rint= 8 (resolution of interferogram wrapped)

The InWF produts are computed in two geometries (in radar : InWF_radar and in ground geometry : InWF_geo):

Processing Details

The filtering of the wrapped interferogram is done in a sliding window, and it use the coherence as a weigthing.

In the metadata file, the following parameters are the filtering options:

• FilterStrength : Strengh of the filter for the Goldstein filter

• filterstyle : the filter selected

• SWwindowsize : width of subwindowths for the filtering

• SWamplim : amplitude threshold
