Mix photos S1

I am working and want to perform Sentinel1 image mixing with optical images (Landsat8 and Sentinel2) on arcmap using Brovey, IHS, and PCA methods, but the result appears error.Can you give me an advice.I take your comments very seriously.

PCAs need equally distributed data in the ideal case. Sentinel-1 ranges between 0 and 0.2 when calibrated but reaches large values beyond 1. Sentinel-2 ranges between 0 and 1 but when imported as integer, such as in ArcMap, the values are 0-10000.

Could also be a matter of projection.

Please explain what processing steps you applied to both data and what error message you get.
