汽车雷达场景仿真方法的研究

Research on the Scenario Simulation Method of Automobile Radar

文章基于电大尺寸电磁波仿真技术,提出民一种能够根据电磁波仿真结果 S参数计算出实际雷达回波信号的方法。该方法能够模拟运动在多目标复杂场景下的雷达回波信号,综合了天线参数、目标RCS变化和地面多径影响等多方面因素。将仿真结果与实测进行对比发现,二者吻合较好,证明了仿真结果的正确性与可靠性。由于仿真工具可以在不进行实车测试的情况下提供准确的雷达数据用于优化雷达算法,文中建立的场景仿真方法可大幅提高毫米波雷达研发的验证效率。

Millimeter wave radar scenario imaging simulation is an important part in design and verification of self-drive vehicle.In this paper,a method base on the electromagnetic wave simulation technology of large electric size is described,which can calculate the actual radar signal by using the electromagnetic wave simulation S parameter results.This method can simulate the radar signal in the complex scene with multiple moving targets,and combines the antenna parameters,target RCS change,ground multi-path influence and other factors.The simulation results are in good agreement with the actual measurements,which proves the correctness and reliability of the simulation results.As the simulation tool can provide accurate radar data to optimize the radar algorithm without real vehicle test,the scene simulation method established in this paper can greatly improve the efficiency of MMW radar research and development verification.
