I am implementing a FMCW radar using bladerf sdr: enter image description here

When reading the output from the vector sinks, the outputs are not synchronised.How should I synchronise them? is it possible to do so using gnuradio only or should I write some HDL code?

EDIT rx signal: enter image description here

tx signal: enter image description here

The object distance is only few meters. The x scale is in seconds. That cant be the delay.

  • $\begingroup$ In what sense they are not synchronised? Is it possible to add some plots to your post showing this lack of synchronisation? $\endgroup$

  • $\begingroup$ added several plots of tx and rx signals, you can see that the delay between them. that is the time scale from gnuradio. $\endgroup$
