摘要
为明晰公开道路高级辅助驾驶系统(ADAS)软体目标物的雷达散射截面(RCS)特征,选取现阶段市面上主流测试目标物,参考ISO19206 目标物研发标准,基于 77GHz大陆 408 毫米波雷达和雷达小车,在封闭场地内开展不同目标物雷达散射截面测试,通过均值及滑移滤波算法处理测试数据,剖析数据耦合因素.结果表明:受多径效应影响,目标物在近场的RCS特征值会迅速下降;在4-40m的距离下,小孩目标物RCS区间为[-9,3]、成人目标物RCS区间为[-7,4],自行车目标物RCS区间为[-3,11];在4-100m的距离下,假车目标物RCS区间为[8,16],货车目标物区间为[20,45],为相关目标物或智驾系统开发提供参考.
Abstract
In order to clarify the radar cross section characteristics of Advanced Driving Assistance system software targets on the open road,the study selects the mainstream test objects in the market at the present stage,referring to the ISO19206 target research and development standard,based on the 77GHz continental 408 millimeter wave radar and radar car.The study carries out the radar scattering cross section test of different targets in the closed field,and processes the test data through the mean value and slip filtering algorithm.The study also analyzes the data coupling factors.The results show that the RCS characteristic value of the target in the near field decreases rapidly due to the multipath effect.At a distance of 4-40m,the RCS interval of child target is[-9,3],that of adult target is[-7,4],and that of bicycle target is[-3,11].At a distance of 4-100m,the RCS interval of vehicle target is[8,16],and that of truck target is[20,45],providing reference for the development of related target or intelligent driving systems.
