In this paper an ultrawideband near range 3D-SAR imaging system using a 80 GHz radar is presented and the effects of radar position errors on the 3D image quality are investigated in detail. Position errors of the radar during the measurement are caused by vibration or oscillation of the moving platform, on which the radar is mounted. In the ideal case, a regular 2D-grid of measurement points is required to synthesize a two dimensional aperture for 3D-SAR reconstruction. Simulated quadratic, sinusoidal and statistic errors have been added to the ideal measurement to analyze the effects on the 3D-SAR image.
