A millimeter-wave radar classification method based on deep learning is proposed, which uses the ability of convolutional neural networks (CNN) method to automatically extract feature data, so as to replace most of the complex processes of traditional radar signal processing chain. Experiments on a real-world dataset demonstrate the ability to distinguish relevant objects from different viewpoints. The method provides object class information such as pedestrian, cyclist, car, or non-obstacle.

In addition to high accuracy, it is crucial for decision making in autonomous vehicles to evaluate the reliability of the predictions; however, decisions of DL networks are non-transparent. Deep learning is making major advances in solving problems that have resisted the best attempts of the artificial intelligence community for many years, and will have many more successes in the near future because it requires very little engineering by hand and can easily take advantage of increases in the amount of available computation and data. The obtained measurements are then processed and prepared for the DL algorithm.

This letter presents a novel radar based, single-frame, multi-class detection method for moving road users (pedestrian, cyclist, car), which utilizes low-level radar cube data and demonstrates that the method outperforms the state-of-the-art methods both target- and object-wise. Before employing DL solutions in safety-critical applications, such as automated driving, an indispensable prerequisite is the accurate quantification of the classifiers' reliability. Reliable object classification using automotive radar sensors has proved to be challenging. Astrophysical Observatory, Electrical Engineering and Systems Science - Signal Processing. Each track consists of several frames. 4 (c). Experimental results with data from a 77 GHz automotive radar sensor show that over 95% of pedestrians can be classified correctly under optimal conditions, which is compareable to modern machine learning systems. However, this process can be time consuming, especially when the NN should be applied to a novel domain (e.g.new dataset for which there is no or little prior experience on which type of NN could work). This paper introduces the first true imaging-radar dataset for a diverse urban driving environments, with resolution matching that of lidar, and shows an unsupervised pretraining algorithm for deep neural networks to detect moving vehicles in radar data with limited ground-truth labels. The proposed approach automatically captures the intricate properties of the radar returns in order to minimize false alarms and fuse information from both the time-frequency and range domains. To the best of our knowledge, this is the first time NAS is deployed in the context of a radar classification task.
