Abstract : This paper studies the influence of phase noise (PN) on radar signal focusing and SAR tomography. Firstly, we create and add PN to simulated data for 1D focusing. A quasi-linear degradation of resolution is observed for 1 kHz PN level higher than -22 dBc/Hz. Secondly, PN is added to multi channel measured data showing that I kHz PN level higher than -60 dBc/Hz affects SAR tomographic reconstruction quality.
