Radarsat2 SLC calibration problem

aisyahrasyid · October 17, 2018, 9:00am

Hi everyone,

I am having a problem when calibrating the SLC of Radarsat 2 data using SNAP as in the picture below. I have tried to save in complex product as shown in the SAR basic tutorial of the Sentinel-1 toolbox. Anyone could help me.

Thanks!

your PC either doesn’t have enough RAM or cannot access it properly: Error when calibrating Sentinel 1 data “cannot construct data buffer”

You need to tweak JVM and cache parameters in the Options. @lveci should be able to advice.
