I would like to view SAR imagery in a SICD file in QGIS. I am able to load the file and view it as a singleband gray image, but the image does not look correct - features are not detectable and the image looks grainy. I've worked with the min/max adjustments, but that hasn't helped. I've seen posts of others using SAR imagery that look great and the text simply says to load the image and then details are given for further processing. Could someone please provide the necessary steps to load SICD images in QGIS?
