Experimental Verification of a 77-GHz Synthetic Aperture Radar System for Automotive Applications

We present measurement results collected with an experimental 77-GHz synthetic aperture radar, which is suitable for automotive applications. The presented approach relies on a simplified signal processing algorithm, which is derived by exploiting several approximations valid for typical automotive measurement settings. This leads to an image generation approach which requires only limited computational power. The presented results show that, despite the simplified approach, meaningful radar images can be generated. The experimental data was collected during various test drives without requiring highly precise position information.
