摘　　要：为了分析汽车发出的电磁波对2.4 GHz无线通信的干扰作用,讨论了汽车的几种辐射性电磁干扰源,并用频谱分析仪实际测量两种汽车在2.4 GHz频段上辐射性电磁干扰的相对强度,测量结果表明,汽车在2.4 GHz频段发出的电磁干扰强度很小,可以推断汽车对车载2.4 GHz无线通信的影响作用不大。In order to analyze the disturbance effect of electromagnetic wave emitted by autos on 2.4 GHz wireless communication,several radiated electromagnetic interference sources are discussed,and the spectrum analyzer is applied to mea-sure the relative disturbance intensity of radiated electromagnetic interference in 2.4 GHz on two different autos.The mea-surement results indicate that there is little disturbance effect on 2.4 GHz wireless communication,from which it concludes that autos can not disturb the 2.4 GHz wireless communication.

关 键 词：汽车 电磁干扰 无线通信 干扰强度
