Towards Multi-Object-Tracking with Radar on a Fast Moving Vehicle: On the Potential of Processing Radar in the Frequency Domain
This paper argues for processing automotive radar data in the frequency domain to improve robustness for multi-object tracking (MOT) on fast-moving vehicles. Traditional feature-based methods struggle with radar's low resolution, noise, and interference. Frequency domain processing, specifically using methods like Fourier-SOFT (FS2D), offers superior robustness by utilizing information across different scales and inherently identifying all moving structures via correlation peaks. This eliminates the need to a priori know the number of dynamic objects and simplifies object detection. Initial experiments using the Boreas dataset with FS2D demonstrate successful radar-only odometry, even in dynamic scenes, supporting the method's potential for challenging applications like autonomous overtaking.
Executive Impact: Enhanced Perception for Autonomous Systems
Leveraging frequency-domain radar processing significantly boosts the reliability and accuracy of object tracking in challenging automotive environments, directly contributing to safer and more capable autonomous driving.

Autonomous Overtaking with Frequency-Domain Radar
Autonomous overtaking is a critical and challenging maneuver for ADAS and autonomous racing. It requires precise tracking of multiple dynamic objects (ego-vehicle, overtaken vehicle, surrounding traffic). Traditional vision/lidar methods can be affected by weather. Radar, especially when processed in the frequency domain, offers a robust solution for tracking these objects simultaneously and accurately. The inherent ability of methods like FS2D to detect all moving structures through correlation peaks simplifies the MOT problem significantly, even in high-velocity scenarios.
