摘　　要：在介绍了侧装机动车雷达测速仪基本工作原理的基础上，分析了侧装雷达测速仪在实际工作中存在现场测速误差的原因，研究了满足现场测速误差要求的天线计量关键技术指标：水平主瓣宽度不超过6°，通过2款侧装雷达测速仪在真实交通情况下的现场试验结果，验证了满足天线水平主瓣宽度不超过6°的侧装雷达测速仪在实际工作中的测量结果更为准确可靠，其现场测速误差能够满足我国相关技术法规的要求。The principle of across-the-road vehicle radar speed-measuring device is presented. The cause for the speed-measuring error in actual traffic is analyzed, and then the antenna key metrological technical parameters, the mainlohe heamwidth in the horizontal plane shall not exceed 6°, which should be satisfied to meet actual speed-measuring error limit, are studied. It has been proved by the test results of two types of across-the-road radar in actual traffic. During the measurement, if the mainlohe beamwidth in the horizontal plane does not exceed 6°, the measuring results are more accurate and reliable. Therefore, it can meet the technical requirements laid down in the relevant national verification regulation and technical standards.
