Title
(EN) RADAR-IMAGE SHAPER FOR RADAR-BASED APPLICATIONS
(FR) FAÇONNEUR D'IMAGE RADAR POUR APPLICATIONS RADAR
Abstract
(EN)
This document describes techniques and systems that enable a radar-image shaper for radar-based applications. A radar field (110) enables an electronic device (102) to accurately determine a characteristic disposition (e.g., a location, orientation, velocity, or direction) of an object (112) in the radar field. The characteristic disposition is determined by detecting a radar signature (or cross-section) of a radar-image shaper (114, 802, 804, 1204, 1206) of the object. The shape of the radar-image shaper produces a known signature when illuminated by the radar field. Determining the characteristic disposition of the object with these techniques allows the object to be used to interact with the electronic device using gestures and other position-based techniques. Because the radar-image shaper enables a passive object to control applications on the electronic device, users have an interaction method with a rich library of gestures and controls that do not require additional components or a battery.

La présente invention concerne des techniques et des systèmes qui permettent un façonneur d'image radar pour des applications faisant appel à un radar. Un champ radar (110) permet à un dispositif électronique (102) de déterminer avec précision une disposition caractéristique (par exemple, un emplacement, une orientation, une vitesse ou une direction) d'un objet (112) dans le champ radar. La disposition caractéristique est déterminée par détection d'une signature (ou section transversale) radar d'un façonneur d'image radar (114, 802, 804, 1204, 1206) de l'objet. La forme du façonneur d'image radar produit une signature connue lorsqu'il est éclairé par le champ radar. La détermination de la disposition caractéristique de l'objet avec ces techniques permet d'utiliser l'objet pour interagir avec le dispositif électronique à l'aide de gestes et d'autres techniques basées sur la position. Étant donné que le façonneur d'image radar permet à un objet passif de commander des applications sur le dispositif électronique, les utilisateurs disposent d'un procédé d'interaction avec une riche bibliothèque de gestes et de commandes qui ne nécessitent pas de composants supplémentaires ni de batterie.
