Wrong LatLon coordinates in merge_tops_bursts process for multi-bursts #247

Open lidar-nevermore opened 4 weeks ago

lidar-nevermore commented 4 weeks ago

I'm merging four bursts in tianjin, China: S1_146288_IW1_20180323_20180404_VV_INT40_2A34 S1_146288_IW2_20180323_20180404_VV_INT40_645D S1_146289_IW1_20180323_20180404_VV_INT40_34DF S1_146289_IW2_20180323_20180404_VV_INT40_1F71

The unwrapping and corr images are correct. Here is an example for merge/phsig.cor 2024-09-06 093712

But the Lon.rdr lat.rdr and los.rdr are wrong. See e.g. the merge/lat.rdr 2024-09-06 093744

As a result, the lv_phi.tif and lv_theta,tif in the merged products are also wrong. The following is an overlay of lv_phi.tif on corr.tif

Moreover, when applying the water mask, it will lead to errors when transform the mask from wgs84 to radar coordinate systems.
