Title
(EN) RADAR DEEP LEARNING
(FR) APPRENTISSAGE PROFOND POUR RADAR
Abstract
(EN)
Disclosed are techniques for employing deep learning to analyze radar signals. In an aspect, an on-board computer of a host vehicle receives, from a radar sensor of the vehicle, a plurality of radar frames, executes a neural network on a subset of the plurality of radar frames, and detects one or more objects in the subset of the plurality of radar frames based on execution of the neural network on the subset of the plurality of radar frames. Further, techniques for transforming polar coordinates to Cartesian coordinates in a neural network are disclosed. In an aspect, a neural network receives a plurality of radar frames in polar coordinate space, a polar-to-Cartesian transformation layer of the neural network transforms the plurality of radar frames to Cartesian coordinate space, and the neural network outputs the plurality of radar frames in the Cartesian coordinate space.

L'invention concerne des techniques d'utilisation de l'apprentissage profond pour analyser des signaux radar. Selon un aspect, un ordinateur embarqué d'un véhicule hôte reçoit, en provenance d'un capteur radar du véhicule, une pluralité de trames radar, exécute un réseau neuronal sur un sous-ensemble de la pluralité de trames radar et détecte un ou plusieurs objets dans le sous-ensemble de la pluralité de trames radar sur la base de l'exécution du réseau neuronal sur le sous-ensemble de la pluralité de trames radar. L'invention concerne en outre des techniques de transformation de coordonnées polaires en coordonnées cartésiennes dans un réseau neuronal. Selon un aspect, un réseau neuronal reçoit une pluralité de trames radar dans un espace de coordonnées polaires, une couche de transformation de coordonnées polaires en coordonnées cartésiennes du réseau neuronal transforme la pluralité de trames radar en espace de coordonnées cartésiennes et le réseau neuronal délivre la pluralité de trames radar dans l'espace de coordonnées cartésiennes.
