Process TanDEM-X with ISCE2

[ES20180816]

Hello everyone,

I am trying to process a group of bistastic TanDEM-X images according to the insarApp.py.

However, when I run the code of "make_raw", there is one error as "iscesys.Component.PortError: 'No input port named sensor", as shown below

def setTDX(info):
... objSensor = createSensor('TANDEMX')
... objSensor.xml = getInfo(info, 'xml')
... objSensor.output = getInfo(info, 'output')
... # set Doppler
... objDop = createDoppler('usedopIQ')
... #dict_keys(['USEDOPIQ', 'USECALCDOP', 'USEDOPPLER', 'USEDEFAULT'])
... return objSensor, objDop
...
def make_raw(sensor, doppler):
... from make_raw import make_raw
... objMakeRaw = make_raw()
... objMakeRaw(sensor=sensor, doppler=doppler)
... return objMakeRaw
...
(objSensor, objDop) = setTDX(masterXml)
sarMeta = make_raw(objSensor, objDop)

If anyone can give some suggestions for solving this problem I would be very appreciative.

The TanDEM-X CoSSC processing is not implemented in either the stack processor nor stripmapApp

Ok, thank you.

There are no prepackaged workflows for bistatic data but there are a couple of modules that can be used with python scripts to do the custom processing.

Ok, I have got it. Thank you very much.
