Thermal Noise Removal in Sentinel-1 EW products

This is the name of my product:S1A_EW_GRDM_1SDH_20180719T072036_20180719T072140_022860_027A98_C108.
My question is how to effectively remove the vertical stripes, like the kirill.s’ s image. I’ve tried this method: thermal noise removal->speckle filtering->radiometric calibration. But it didn’t work out so well.
There are results.Can you help me with this problem, please?
