I have just reviewed the previous acquisitions we had for TerraSAR X and our current ones @ABraun @mengdahl, and I have noticed that we changed the parameters of the acquisitions. The first two or three images had a low incidence angle , while subsequent images had an adjusted higher angle to 45° to improve the range resolution to 0.85m. Is it still possible to use a multi-temporal filter on this data or will the change in angle effect this too much?
As for the geometric issue @css, I opened the image in google maps and the flat areas to appear to match relatively well with the Google imagery, I have no managed to get a building measurements much closer to their actual size (within about 2m). The object does appear to be a ship, as shown in the pleiades tri stereo image captured around the same time. The distortion must be introduced by the terrain correction
