Compared to lidars and cameras, automotive-legacy radars can work in any weather condition and without an external source of illumination, but are limited in either range or angular resolution.  ...  SARs offer a relevant increase in angular resolution, provided that the ego-motion of the radar platform is known along the synthetic aperture.  ...  Fig. 3 . 3 Fig. 3. Test 1: set of single-beam SAR images RGB coded: 0 deg in red, 5 deg in green, 20 deg in light blue (images not in scale). DFig. 4 . 4 Fig. 4.  ...
