Abstract
With deep learning based perception tasks on radar input data gaining more attention for autonomous driving, the use of new data interfaces, specifically range-beam-doppler tensors, are explored to maximize the performance of corresponding algorithms. Surprisingly, in past publications, the Doppler information of this data has only played a minor role, even though velocity is considered a powerful feature. We investigate the hypothesis that the sensor ego-velocity, induced by the ego vehicle motion, increases the data generalization complexity of the range-beam-doppler data and propose a phase shift of the electromagnetic wave to normalize the data by compensating for the ego vehicle motion. We show its efficacy versus non-compensated data with an improvement of 8.7% average precision (AP) for object detection tasks.
