I am curious about the beat signal frequency.
Assuming a simple radar system.
Let's say RF freq is 100M, so its period is 10ns.
LO has the same freq, i.e. 100M, but LO phase is 500ps delayed, that is 1/20 of period.
AFter the mixer, get the beat signal,
1. so how to calculate the beat signal freq from above data?
This is just help me to understand the radar beat signal, not a live system.
2. How this beat signal depend on the phase noise of LO?
Thanks.
