汽车零部件的雷达波抗扰度测试

Testing Method of Immunity to Radar Waves for Automotive Components

介绍雷达波辐射场抗扰度测试方法,指出雷达波测试是汽车零部件抗干扰能力的有效验证方法。阐述在测试布置、校准和信号调制三个方面与一般辐射场抗扰度测试的不同,认为场强高、校准难度大、脉宽窄是产生差异的主要原因。

The radar-wave immunity test for automotive components is introduced briefly,which contrasts with the ordinary radiated immunity testing method in the way of test setup,calibration and signal modulation.It is proved that immunity test using radar wave is an effective validation method.Finally,the reasons of the differences between radar-wave test and traditional immunity test are concluded as higher field strength,higher difficulty for calibration and narrower pulse width.
