Title (EN) INCREASING PERFORMANCE OF A RECEIVE PIPELINE OF A RADAR WITH MEMORY OPTIMIZATION
(FR) AUGMENTATION DE LA PERFORMANCE D'UN PIPELINE DE RÉCEPTION D'UN RADAR AVEC OPTIMISATION DE MÉMOIRE
Abstract:
(EN) A radar sensing system for a vehicle includes transmitters, receivers, a memory, and a processor. The transmitters transmit radio signals and the receivers receive reflected radio signals. The processor produces samples by correlating reflected radio signals with time-delayed replicas of transmitted radio signals. The processor stores this information as a first radar data cube (RDC), with information related to signals reflected from objects as a function of time (one of the dimensions) at various distances (a second dimension) for various receivers (a third dimension). The first RDC is processed to compute velocity and angle estimates, which are stored in a second RDC and a third RDC, respectively. One or more memory optimizations are used to increase performance. Before storing the second RDC and the third RDC in an internal/external memory, the second and third RDCs are sparsified to only include the outputs in specific regions of interest.
(FR) L'invention concerne un système de détection radar pour un véhicule comprenant des émetteurs, des récepteurs, une mémoire et un processeur. Les émetteurs émettent des signaux radio et les récepteurs reçoivent des signaux radio réfléchis. Le processeur produit des échantillons en corrélant des signaux radio réfléchis à des répliques différées de signaux radio émis. Le processeur stocke ces informations sous la forme d'un premier cube de données radar (RDC), avec des informations relatives à des signaux réfléchis par des objets en fonction du temps (une des dimensions) à différentes distances (une deuxième dimension) pour différents récepteurs (une troisième dimension). Le premier RDC est traité pour calculer des estimations de vitesse et d'angle, qui sont stockées dans un deuxième RDC et un troisième RDC, respectivement. Une ou plusieurs optimisations de mémoire sont utilisées pour augmenter la performance. Avant de stocker le deuxième RDC et le troisième RDC dans une mémoire interne/externe, les deuxième et troisième RDC sont clairsemés pour ne comprendre que les sorties dans des régions d'intérêt spécifiques.
