Jason, You are right my question about switching between tx and rx only makes sense if it is no possible to tx and rx at the same time.
Since you told me it is possible to it at the same frequency (that means small doppler frequency shifts) the system looks promissing. I was afraid of wasting most of the time of my unambiguous radar range waiting to the system to switch to reception mode. Many thanks, Jorge.
