Offset Tracking (ERS)

Microwave Toolbox
#1

While doing offset tracking on a pair of coregistered ERS-1 data pair (DEM assisted), I get the following message “Cannot find master or slave amplitude or slave bands”. Can anybody suggest what went wrong.

NullPointerException when using Offset Tracking

#2

what product level are you using for this?

They are defined here.

#3

ERS-1 - SAR Level 1 Single Look Complex Image Product
(SAR_IMS_1P) downloaded using EOLISA

#4

I don’t know if this caused the error but it was recently discussed and found that ground range data is the more accurate input for offset tracking: Offset Tracking : SLC vs GRDH products
In your case, it’s the SAR_IMP_1P product.

Can you please name the product names of your input data?
