I'm trying to model the radar signal but I can't figure out how to reduce the received signal to IF frequency. Can you help?

Hi Adem

I understand that you are trying to down-convert your received Radar signal to an IF frequency.

While transmitting your Radar signal you must have upconverted your signal with a carrier frequency. Multiplying your received Radar signal with cos(2*pi*fc*t), where ‘fc’ is carrier frequency and appropriate high pass filtering will down-convert your received signal to IF frequency.

Hope this resolves your query.
