Accurate FMCW radar-based indoor localization system

An accurate ranging system based on FMCW (Frequency Modulated Continuous Wave) Radar is presented. The system ensures a centimetre precision even in environments with high multipath, such as warehouses packed with metallic objects or extremely dusty sites where conventional RF, laser, ultrasonic or video technologies present severe limitations. The proposed solution has been experimentally applied in Automatic Guided Vehicle for warehouses. The architecture of the system and the obtained results are presented in detail.
