Abstract

La présente divulgation concerne des procédés et des appareils de détection, un système de détection, un dispositif de communication et un support de stockage. Un procédé de détection consiste à : recevoir des premières informations, les premières informations étant utilisées pour indiquer un premier moment et un second moment ; et envoyer des secondes informations à un premier dispositif de communication, les secondes informations comprenant des informations de sous-espace pour estimer la quantité de détection d'un diffuseur ou d'une cible qui change entre le premier moment et le second moment. Les modes de réalisation de la présente divulgation peuvent atténuer fortement ou même éliminer complètement les interférences provenant de diffuseurs/cibles connus et se focaliser plutôt sur un diffuseur/une cible qui change dans une période de temps donnée, ce qui facilite le déclenchement d'un événement prédéfini sur la base de changements dans le diffuseur/la cible, et facilite également la mise en œuvre d'une combinaison souple sous une structure de détection collaborative, et améliore ainsi la précision de détection.
