Error:Slant range to ground range about TerraSAR

Hi everyone
I meet a error when I use “complex to detected GR” to process TerraSAR SM level1B(SLC). Can someone help me solve the problem?

@lveci @marpet @mengdahl @ABraun @mfoumelis can you tell me how to solve the problem?

Is Range Doppler Terrain Correction an alternative option?

I’m not sure. So I should try “Range Doppler Terrain Correction”?

Yes, it probably does what you need and you can select ro output complex data as well.
