I need help in wireless Distance proportional Signal System

What i need is clearly explained in this diagram

Now, What i need is two circuits A and B

As show in the diagram B must be a emitter or watever
A must get the signals from B and must display (or output a value to Micro Processor) which is proportional to the distance between A and B.
So when i move the circuit B .. the value in A must change accordingly

I need your suggestions and help
I am a complete Noob in this, I am from Computers department

Hoping for help
Thanks :)

( Sorry , If I posted in wrong forum )

You didn't say how far "x" might be, and what interference there might be between A and B. For short and unobscured distances, you could just get one of those ultrasonic range finders or laser "tape measure".
