How to perform Tasseled Cap Function/"Greenness" Factor in GIS?

Good morning,

 

I'm a beginner analyst attempting to map impervious water surfaces of land parcels in a city. The research I did suggested I use what is called the "Tasseled Cap" function in GIS to estimate the vegetation aka "Greenness" factor of the raster image to automatically make a distinction between pixels that are vegetation (some minimum level of green) and not vegetation (impervious).

 

I have no idea how to do this as my experience with Python and SQL is extremely limited and I can't find a built in function to do this for me.

 

Would anyone happen to have any helpful hints?

 

Cheers
