he radar system at an airport broadcasts 11 GHz with 150 kW. An approaching airplane with a 34 m^2 cross section is 24km away. Assume that the radar broadcasts uniformly in all directions and that the airplane scatters microwaves uniformly in all directions.What is the electric field strength of the microwave signal received back at the airport 160mu.seconds later?
