Millimeter-wave automotive radar with PLL-generated ramps modelling by using SystemVue and MATLAB

Millimeter wave automotive radar is one of the most important components in the advanced driver assistance system (ADAS), which detects objects around the ego vehicle with moderate cost. Because automotive radar is composed of a vast variety of different components including RF, analog and digital circuits and radar signal processing software, modelling the whole radar system is challenging. This paper presents modelling a whole 24GHz automotive radar by using SystemVue and MATLAB. The ramps of the radar are generated by a phase locked loop. The radar radio frequency frontend and the radar target echo signal are modelled in SystemVue and the radar signal processing is taken place in MATLAB. Influences of the real RF signal source on the radar performance of object detection can be analyzed.
