The radar system at an airport broadcasts 11 GHzGHz microwaves with 150 kWkW of power. An approaching airplane with a 33 m2m2 cross section is 27 kmkm away. Assume that the radar broadcasts uniformly in all directions and that the airplane scatters microwaves uniformly in all directions.
A. What is the electric field strength of the microwave signal received back at the airport 180 μsμs later?

Suppose the maximum safe average intensity of microwaves for human exposure is taken to be 1.00 W/m2. If a radar unit leaks 10.0 W of microwaves (other than those sent by its antenna) uniformly in all directions, how far away must you be to be exposed to an average intensity considered to be safe? Assume that the power spreads uniformly over the area of a sphere with no complications from absorption or reflection. minimum safe exposure distance: mm What is...
