Short Answer

The radar system at an airport broadcasts microwaves with of power. An approaching airplane with a cross section is 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 later?

The electric field strength of the microwave signal received back at the airport later,

See the step by step solution

Step by Step Solution

Step 1: Data given

Step 2: Find the facility density which is received 

The Electromagnetic wave's power flux volume was determined by:

Then we have got,

The intensity of power in airplane,

Power reflected was shown as,

The receiving power density was

Step 3: Find the electrical strength 

Then, we calculate
