| Abstract: | 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 mainlobe beamwidth 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 mainlobe 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. |
