GITASAR: SAR image processing for beginners

Technically, yes. The ionospheric effects can be corrected burst by burst, but it is coherence dependent. The spectrum splitting method is a very popular way to achieve this.

Hi All,

I just successfully imported alos palsar 2 (quad pol) and moving forward to check the baseline and do corregistration, but have some issues

Could you help me why I could not proceed the baseline information or coregistration? The issue is GITASAR has stopped working.Could anyone help me on this?

Thanks Aries, you might need to open the XML file using textbook or Notebook to check out the SENSOR item, you might see this item has an empty value, and please fill it out using “ALOS2”, then it can go throught. Thanks for reporting this bug, and will fix it in the next version. @aries400

Hi @xhuang, would you like me to edit the XML ? I just tried but still, getting error. Herewith attached the XML file metadata_alos2_master.xml (16.4 KB) metadata_alos2_slave.xml (16.4 KB)

metadata_alos2_master.xml (16.4 KB) metadata_alos2_slave.xml (16.4 KB)

I have edited the XML for you, please see attached, and I have run it with no problem.


P.s. if you just want to see the outcome, please click the “Test” button. If you need the files, give a directory in “Output Dir”, and Run “OK” @aries400

Hi Again @xhuang , would you like to share how to obtain CPX coherence? I confused why gitasar need master and slave again? Is’nt the CPX coherence based on T6? Does this mean I have to create matrix S2 first
