A. Ouaknine, A. Newson, J. Rebut, F. Tupin, P. Pérez
2021 arXiv   pre-print
In this work, we introduce CARRADA, a dataset of synchronized camera and radar recordings with range-angle-Doppler annotations.  ...  To a large extent, this situation is due to the relative lack of automotive datasets with real radar signals that are both raw and annotated.  ...  ACKNOWLEDGMENT The authors would like to express their thanks to the Sensor Cortex team, which has recorded these data and spent time to answer our questions, and to Gabriel de Marmiesse for his valuable  ...

Multi-View Radar Semantic Segmentation [article]

Arthur Ouaknine, Alasdair Newson, Patrick Pérez, Florence Tupin, Julien Rebut
2021 arXiv   pre-print
In this work, we propose several novel architectures, and their associated losses, which analyse multiple "views" of the range-angle-Doppler radar tensor to segment it semantically.  ...  However, they are seldom used for scene understanding due to the size and complexity of radar raw data and the lack of annotated datasets.  ...  Acknowledgements We thank Veronica Elizabeth Vargas Salas for her valuable help with temporal radar data.  ...

Automotive Radar Processing With Spiking Neural Networks: Concepts and Challenges

Bernhard Vogginger, Felix Kreutz, Javier López-Randulfe, Chen Liu, Robin Dietrich, Hector A. Gonzalez, Daniel Scholz, Nico Reeb, Daniel Auge, Julian Hille, Muhammad Arsalan, Florian Mirus (+3 others)
2022 Frontiers in Neuroscience  
This study proves the general applicability of SNNs for automotive radar processing and sustains the prospect of energy-efficient realizations in automated vehicles.  ...  For radar target detection, an SNN with temporal coding is competitive to the conventional approach at a low compute overhead.  ...  The CARRADA dataset, on the other hand, includes the range-Doppler as well as the range-angle map for each scan.  ...

Raw High-Definition Radar for Multi-Task Learning [article]

Julien Rebut, Arthur Ouaknine, Waqas Malik, Patrick Pérez
2022 arXiv   pre-print
In this paper, we propose a novel HD radar sensing model, FFT-RadNet, that eliminates the overhead of computing the range-azimuth-Doppler 3D tensor, learning instead to recover angles from a range-Doppler  ...  Also, we collected and annotated 2-hour worth of raw data from synchronized automotive-grade sensors (camera, laser, HD radar) in various environments (city street, highway, countryside road).  ...  As the radar signal is difficult to interpret by annotators and practitioners alike, a 16-layer automotive-grade laser scanner (LiDAR) and a 5 Mpix RGB camera are also provided.  ...

Application of Deep Learning on Millimeter-Wave Radar Signals: A Review

Fahad Jibrin Abdu, Yixiong Zhang, Maozhong Fu, Yuhan Li, Zhenmiao Deng
2021 Sensors  
Most of the prominent deep learning models exploit data representations acquired with either Lidar or camera sensors, leaving automotive radars rarely used.  ...  This is despite the vital potential of radars in adverse weather conditions, as well as their ability to simultaneously measure an object's range and radial velocity seamlessly.  ...  Recently, the authors of [44] presented a CARRADA dataset comprising a synchronized camera and low-level radar recordings (Range-Angle and Range-Doppler radar representations) to motivate deep learning  ...

2022 arXiv   pre-print
With the development of automotive radar technologies in recent years, instance segmentation becomes possible by using automotive radar.  ...  Automotive radar provides reliable environmental perception in all-weather conditions with affordable cost, but it hardly supplies semantic and geometry information due to the sparsity of radar detection  ...  As a result, RadarScenes [1] dataset is selected to validate the proposed methods. The dataset contains data from four front-mounted near-range automotive radars, one camera, and one odometer.  ...
