Find the diameter of the radar beam

Reference no: EM13249102

A radar for tracking aircraft broadcasts a 12.0GHzmicrowave beam from a 2.00m -diameter circular radar antenna. From a wave perspective, the antenna is a circular aperture through which the microwaves diffract.

What is the diameter of the radar beam at a distance of 30.0km?

If the antenna emits 100kW of power, what is the average microwave intensity at 30.0km?
