Hello all,
I am working on designing a X-band radar for motion detection. Problem I am facing now is that I will have multiple Tx/Rx channels(connected to diferent antennas) running(pulsed radar) and I need to synchronize or lock them to each other somehow. I have some ideas but not sure which one would work.
1-) A way to synchronize different VCO's to each other. I checked out some PLL's, however in their datasheet RefinA and RefinB refers to complementary signals and not two distinct signals.
Can anyone suggest a way to do it?
2-) Using a switch to alternate between Antennas; however, due to high power nature of PA, I'm not sure what would be the effect of thermal memory on that.
3-) Using a N-way Divider at the output of VCO, then using the divided signals as Tx_signal in different channels.
Ideas are appreciated on the matter.
Kind Regards,
ktr
