Phase Noise Influence on Radar Signal Focusing and SAR Tomography

Résumé

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.
