As a retired communications systems engineer, my response to the above is
Terrestrial microwave (signals transmitted from one terrestrial site to
another as apposed to satellite up links) NEVER exceed about ten watts.
those in the band mentioned (1.8 to 2.0 Ghz) usually have a one watt
transmitter. A few very long range paths over water or from one mountain
top to another, will have up to ten watts.
While it is not a good idea to stand for extended periods directly in
front of such transmit antennas, and at a distance of less than ten feet,
Once out past the ten foot point, the total power level is well below that
of the old USSR regulation which was ten times the limit set for the US and
was the lowest limit in existence.
Those who work in very close proximity to microwave antennas and
microwave equipment have been known to have a slightly (about one-half of
one percent) higher risk of developing various diseases such as tumors,
cataracts, and so on. That is those who spend their entire working life,
or at least many years, in such conditions.
BTW, almost none of these systems use pulsed modulation. RADAR uses
pulsed modulation by design. It also uses much higher power levels. An
exception is Doppler RADAR used by police to catch speeders. Although this
can be pulsed, it is also very low power. Larger RADARs such as weather
and airport type systems do use high power. Stay at least 200 feet away
from those antennas.
