Simple SummaryContent extracted from patent full text and abstract with AI.

The patent describes a method for locating a moving object using a chipless, passive transponder that is coded with several areas having different polarimetric properties. When the transponder is illuminated by a radar station with polarized electromagnetic waves, the reflected waves create a polarization-coded image. This allows the radar station to identify the transponder, and consequently, determine the current position of the moving object. The patent also covers the specific design of such transponders.

Use CasesContent extracted from patent full text and abstract with AI.

  • Asset tracking in logistics and supply chain management
  • Monitoring the movement of vehicles or equipment in industrial or warehouse settings
  • Tracking luggage or containers at airports and seaports
  • Security applications for identifying and locating tagged articles
  • Tracking items in automated production or storage systems

BenefitsContent extracted from patent full text and abstract with AI.

  • Enables accurate location tracking without the need for battery-powered or chipped devices
  • Reduces maintenance cost due to the use of passive (battery-free) components
  • Difficult to tamper or disable, enhancing security and reliability
  • Enables identification and tracking even in challenging environments where electronic tags may fail
  • Scalable and suitable for tracking large numbers of objects simultaneously

Patent Abstract

Es wird Verfahren zur Ortung eines beweglichen Objektes (1) angegeben, bei dem ein chiploser, passiver Transponder (3, 31), der durch mehrere Teilflächen (6, 7, 8, 9) mit unterschiedlicher polarimetrischer Eigenschaft codiert ist, von einer Radarstation (5) mit polarisierten elektromagnetischen Wellen bestrahlt wird, wobei der Transponder (3, 31) oder die Radarstation (5) auf dem Objekt (1) angeordnet ist, von der Radarstation (5) die am Transponder (3, 31) reflektierten Wellen erfasst werden, aus den reflektierten Wellen ein polarisationskodiertes Bild erzeugt und der Transponder (3, 31) anhand des polarisationskodierten Bildes erkannt wird, anhand des erkannten Transponders (3, 31) das Objekt (1) identifiziert und auf eine aktuelle Position des identifizierten Objektes (1) geschlossen wird. Weiter wird ein entsprechender Transponder (3, 31) angegeben.
