If say I wish to measure a radar's 2 port characteristics (it sends to itself via a distance D air link)
Can I make an experiment that I use Network Analyzer to measure it transmitting signal to another antenna B spacing distance D LOS, then cascade the resulted s2p file in the configuration such that
[port 1, port 2] --- [port 2 , port 1] , and divided the dB(s21) and dB(s12) by two respectively and subtract by 3 dB to get the 2 port metrics?
I am not quite familiar with the operations/tricks on scattering parameters, could anyone recommend resources that I can refer to?
Thank you very much!
