摘要
复杂目标在高频区具有多散射中心特性,而目前针对车载毫米波雷达的射频仿真测试多以点目标仿真为主,仿真精度较低。对此,通过分析复杂目标的多散射中心特性,提出基于体目标雷达截面积的毫米波雷达道路场景仿真方法。这一方法通过体目标雷达截面积的预估和位姿信息的计算,对特定场景下的多散射点位姿序列进行求解,实现道路场景仿真要求。基于场景实例对这一方法的可行性进行了验证。
Complex target has the characteristics of multiple scattering centers in the high-frequency region,and the current RF simulation test for the vehicle-mounted millimeter-wave radar mostly focus on point target simulation,and the simulation accuracy is low.In this regard,by analyzing the characteristics of multiple scattering centers of the complex target,a millimeter-wave radar road scene simulation method based on body target radar cross-sectional area was proposed.This method uses the estimation of the radar cross-sectional area of body target and the calculation of the pose information to solve the multi-scattering point pose sequence in a specific scene,and realize the requirement of road scene simulation.The feasibility of this method was verified based on a scenario example.
