I am working on a project to interface 2 RF antennas (TX and RX) with the pi3 working on RF frequency band (2GHZ - 2.5GHZ).
The question is: how to basically interface an antenna with a microcontroller (raspberry in my case), send interrogation signal through TX antenna and receive an RCS graph, to be later analyzed, from the RX antenna? I have no idea where to start since the GPIOs are digital.
I am a beginner here and hope someone can advice me with the correct interfacing peripheral.
looking forward for your responses, thanks in advance.
