FMCW RADAR SYSTEM AND RADAR SENSOR OPERATION METHOD IN FMCW RADAR SYSTEM

摘要

Disclosed are an FMCW radar system and a radar sensor operation method in the FMCW radar system. According to the embodiments of the present invention, by controlling Doppler reflective signals from radar sensors installed in an autonomous vehicle to be received in order in a time-sharing mode, the interference among the installed radar sensors is minimized so that the performance of the radar sensor can be enhanced. Aosl the load on a CPU is reduced so that the CPU can be operated efficiently. Furthermore, by calculating the Doppler speed from the clutter signals received from the installed radar sensors and then finally calculating the installation angle of the multiple radar sensors, the target finding accuracy of the radar sensors can be improved.;COPYRIGHT KIPO 2014;[Reference numerals] (AA) Start; (BB) End; (S10) Control Doppler reflective signals to be received in order in a time-sharing mode; (S20) Calculate the Doppler speed from the clutter signals included in the Doppler reflective signals; (S30) Calculate the installation angle of the multiple radar sensors based on the Doppler speed and the vehicle speed
