I had a hunch that was a c&p job - it was too fast and too glib. It also explains the
statute miles - trawler jockeys use baby miles in the ICW.

That's easy - here's a more complete answer than the other one I
just gave you.

Beam width is important in bearing resolution. All targets are
widened by the effective horizontal beam width. If the beam width
is 4 degrees, two targets that are one mile off will appear as one
if they are closer together than 370 feet. At two miles the targets
must be separated by 740 feet, at 24 miles a six degree beam width
would merge objects that were almost 1.68 miles apart. This can
make interpretation of the display difficult. Suppose you are
trying to find a harbor mouth that is 370 feet wide. Radar won't
pick it up until you get closer than a mile.

Get it?
