Do you mean the intersection of radio beams or projected directional
You might try a slight modification of r.transect to have it output
end points. (grab the CVS version, it's broken in 5.0.2)

You might try r.los with max_dist= or r.cva. I've also got a version of
r.los I modified to return azimuth instead of elevation if that is of
any use to you. Note r.los is highly inefficient for larger rasters.
