Instability of oscillator can introduce phase noise to the signal received by radar [1].

Are there commonly used digital signal processing methods can reduce the phase noise?

  • $\begingroup$ If you're worried about phase noise for range estimation, you can use multi-pulse integration. I think either coherent or non-coherent integration would help although usually coherent integration is better if you want improved SNR. $\endgroup$
