RADDet: Range-Azimuth-Doppler based Radar Object Detection for Dynamic Road Users [PDF]
Canadian Conference on Computer and Robot Vision, 2021 Object detection using automotive radars has not been explored with deep learning models in comparison to the camera based approaches. This can be attributed to the lack of public radar datasets.
