The performance of automotive radar systems is expected to significantly increase in the near future. With enhanced resolution capabilities more accurate and denser point clouds of traffic participants and roadside infrastructure can be acquired and so the amount of gathered information is growing drastically. One main driver for this development is the global trend towards self-driving cars, which all rely on precise and fine-grained sensor information. New radar signal processing concepts have to be developed in order to provide this additional information. This paper presents a prototype high resolution radar sensor which helps to facilitate algorithm development and verification. The system is operational under real-time conditions and achieves excellent performance in terms of range, velocity and angular resolution. Complex traffic scenarios can be acquired out of a moving test vehicle, which is very close to the target application. First measurement runs on public roads are extremely promising and show an outstanding single-snapshot performance. Complex objects can be precisely located and recognized by their contour shape. In order to increase the possible recording time, the raw data rate is reduced by several orders of magnitude in real-time by means of constant false alarm rate (CFAR) processing. The number of target cells can still exceed more than 10 000 points in a single measurement cycle for typical road scenarios.
