Simulation of the effect of signal source's phase noise on millimeter wave automotive radar system based on SystemVue

Today the advanced driver assistant system and autonomous driving system are very popular. Millimeter wave automotive radar, which can detect objects around the ego vehicle with high accuracy and acceptable cost, is one of the key components of the advanced driver assistant system. Radar performance of detecting objects is greatly influenced by the phase noise of the radar signal source. This paper presents a method to generate numerically radar signal with given phase noise level. This numerically generated radar signal with phase noise can be used in a time domain radar system simulator to simulate the effect of the phase noise on the radar performance of multiple target detection and measurement. The time domain radar system simulator is based on SystemVue which can model the whole automotive radar system including the radio frequency frontend, analog circuits, analog-to-digital converter and radar signal processing algorithms.
