Abstract
In the automotive domain, Forward-Looking Synthetic Aperture Radar (FL-SAR) systems can provide environmental perception, overcoming visibility limitations and integration constraints. However, synthesizing high-resolution cumulative maps from individual FL-SAR snapshots can be challenging, because varying target angles and, thus, angular resolutions between snapshots have to be considered. The presented method addresses this challenge by dynamically weighting and accumulating multiple snapshots, enabling the trade-off between prioritizing measurements with higher resolutions and obscurity issues. Our approach rectifies resolution inconsistencies inherent in FL-SAR systems, enhancing the quality of cumulative maps. We provide an overview of FL-SAR measurements and achievable resolution gains compared to static imaging methods. Our measurement results demonstrate the effectiveness of the algorithm in generating seamless maps, which was validated in real-world scenarios. This research aims to advance the role of FL-SAR as a reliable tool for environmental perception and mapping in automotive applications.
