基于Simulink的无人驾驶汽车雷达的建模与分析

With the development of electronic and information technology, recent years have witnessed a wide concern by people on autonomous driving technology, and radar is one of the most important sensors which the technology relies on. This paper first gives a brief introduction to the current representative autonomous driving technology and the frequency modulated continuous wave (FMCW) radar which is widely used in the automotive field. Then, based on the analysis of the principles and parameters of the FMCW radar, a Simulink model was built, including a signal generation model, a transmitter model, a receiver model and a target model. The model was tested and verified to prove its correctness. At the same time, the frequency spectrum of the beat signal is analyzed. The radar model established in this paper has good versatility, which provides convenience for the design, improvement and testing of updated radar systems.
