Deep Radar Detector
This addresses the need for more efficient and advanced radar processing in autonomous systems, though it appears incremental as it adapts deep learning to an underexplored modality.
The paper tackles the problem of radar processing lagging behind camera and LiDAR by introducing a deep learning approach that works directly with radar complex data, achieving superior performance in radar 4D detection while maintaining real-time capabilities.
While camera and LiDAR processing have been revolutionized since the introduction of deep learning, radar processing still relies on classical tools. In this paper, we introduce a deep learning approach for radar processing, working directly with the radar complex data. To overcome the lack of radar labeled data, we rely in training only on the radar calibration data and introduce new radar augmentation techniques. We evaluate our method on the radar 4D detection task and demonstrate superior performance compared to the classical approaches while keeping real-time performance. Applying deep learning on radar data has several advantages such as eliminating the need for an expensive radar calibration process each time and enabling classification of the detected objects with almost zero-overhead.
