This paper presents an approach to the segmentation of automotive synthetic aperture radar (SAR) images generated with a state-of-the-art multiple-input multiple-output frequency modulated continuous wave radar. Due to the very high image resolution and large signal-to-noise ratio, it is possible to directly distinguish different free spaces, extended objects, or target areas, such as walls or cars, and point-like targets, including posts and trees. The latter are detected using a constant false alarm rate algorithm, whereas free spaces and target areas are segmented by using Otsu's method after morphologically processing the SAR image. With this simple, filter-based segmentation, the perception of the vehicle's environment can be improved without complex post-processing that is typically required in standard radar gridmaps.
