Title (EN) APPARATUS AND METHOD FOR DETECTING BLOCKAGE OF AN AUTOMOTIVE RADAR SENSOR
(FR) APPAREIL ET PROCÉDÉ DE DÉTECTION DE BLOCAGE D'UN CAPTEUR RADAR AUTOMOBILE
Abstract:
(EN) An automotive radar system and method transmit a plurality of radar signals into a region, detect reflected radar signals, and convert the reflected radar signals into digital data signals. A plurality of range-Doppler maps for the region are generated from the digital data signals, and the plurality of range-Doppler maps are averaged to generate an averaged range-Doppler map for the region. Data points in the averaged range-Doppler map are analyzed to detect blobs in the averaged range Doppler map. If a blob is detected in the averaged range-Doppler map, the radar detector is indicated to be unblocked.
(FR) Un système et un procédé de radar automobile transmettent une pluralité de signaux radar dans une région, détectent les signaux radar réfléchis, et convertissent les signaux radar réfléchis en signaux de données numériques. Une pluralité de cartes de distance Doppler pour la région sont générées à partir des signaux de données numériques, et la pluralité de cartes de distance Doppler sont moyennées pour générer une carte de distance Doppler moyenne pour la région. Les points de données dans la carte de distance Doppler moyenne sont analysés pour détecter des taches dans la carte de distance Doppler moyenne. Si une tache est détectée dans la carte de distance Doppler moyenne, le détecteur radar est indiqué comme étant débloqué.
