Identify location of RF transmitter

Hi,

does anyone know is there any way to identify the spot of RF transmitter?
For example, RC car that has RF receiver on it, follows the signal till it come to spot of RF transmitter?

My goal is to make that car goes from point A to point B linear...

Any tips and ideas are welcome...

Thanks,
Petar
