摘　　要：传统的无线通信测试能力主要面向无线通信子系统,无法覆盖整车级无线通信仿真和测试,无法应对当下无线通信状态下智能网联汽车整车的通信系统测试需求。该公司团队多年来专注于整车无线性能测试的基础理论、测试和误差分析方法完善等研究,结合不同仪表厂商,配合有关合作伙伴公司自主研发全套自动化测试软件,建设了一套可移动式整车级天线和无线OTA(空口性能)性能测试系统解决方案。通过该方案可以为整车级无线通信系统的测试提供一定的参考。The traditional wireless communication test capability is mainly oriented to the wireless communication subsystem,which cannot cover the simulation and testing of vehicle-level wireless communication,and cannot cope with the communication system test requirements of intelligent connected ed vehicles under the current wireless communication state.Common antenna and wireless OTA test systems can be divided into far-field,compact-field,and near-field by field type.Our team has focused on the basic theory,testing and error analysis methods of vehicle wireless performance testing for many years,cooperated with many instrument manufacturers,and independently developed a full set of automated testing software,proposed a set of movable vehicle-level antennas and wireless OTA(aerial performance)performance test system solutions.This scheme can provide a certain reference for the testing of vehicle level wireless communication systems.
