European project RESOLUTION-local positioning systems based on novel FMCW radar

摘要

This paper gives an overview of the European (EU) project RESOLUTION (reconfigurable systems for mobile local communication and positioning). RESOLUTION aims at developing a wireless three-dimensional (3-D) local positioning system with accuracy in the centimeter regime. A novel frequency modulated continuous wave (FMCW) radar principle is employed and co-designed together with common WLAN systems operating around 5 GHz. At 140 MHz bandwidth, measurements demonstrate excellent positioning accuracies of better than 4 cm in an anechoic chamber, and 18 cm in a conference hall with strong multipath and area of 800 m". Because of the high positioning accuracy, real-time ability, and robustness against multipath effects and fading, the system is very well suited for smart factories, robotics, interactive guiding, object tracking and augmented reality.
