Average microwave intensity

Assignment Help Physics
Reference no: EM131062439

A radar tracking aircraft broadcasts a 12 GHz microwave beam from a 2.0 m diameter circular radar antenna. From a wave perspective the antenna can be modelled as a circular hole through which the microwaves diffract.

a. What is the diameter of the radar beam at a distance of 30 km?

b. If the antenna emits 100 kW, what is the average microwave intensity at 30 km?
