Ultra Wide Band Radar sensor systems and method for improved location awareness

摘要

The present invention discloses an ultra-wideband radar sensor system and method for improving position recognition performance by effectively operating a plurality of UWB radar sensors at the same time to determine the position of an object at high speed. The present invention may be composed of a plurality of ultra-wideband radar sensors (UWB radar sensors) that transmit and receive UWB signals, and a host position recognition device that controls the operation of all UWB radar sensors and calculates a position by receiving a measured value. One of the four UWB radar sensors is set to the transmit/receive mode and transmits UWB signals, and all other UWB radar sensors are set to the receive mode and the signal transmitted by the UWB radar sensor set to the transmit/receive mode is reflected to the object. By checking the time, it is possible to calculate the spatial position of the object by calculating the distance traveled to each radar sensor by reflecting the transmission signal. In addition, the radar sensor, which is set in transmission or transmission mode in all radar sensors, is selected and circulated by the host location recognition device, and the host location recognition device sends a synchronization signal to all radar sensors and calculates the synchronization signal time error of each radar sensor. By storing it, the position of the object can be accurately calculated in the future.
