摘　　要：车载电磁辐射监测技术在我国属于新兴的研究性监测技术,可快速、高效地进行区域电磁辐射环境监测。研究了车载监测方式中影响监测结果的主要因素,分析了实验数据,并得出各影响因素的实验结论。通过理论分析、电波暗室测量、实际环境测量等,建立计算和实验模型。计算结果表明,当车辆行驶速度在18 km/h、36 km/h、60 km/h时,车速的大小对测量结果的影响可以忽略不计。车顶反射对车载电磁辐射监测系统有一定的影响。可根据不同测试条件选择合理的车速,在车顶铺设不同材质的吸波材料,减少车顶反射对车载电磁辐射监测系统的影响,保证监测数据的可靠性。The Vehicle-carried electromagnetic radiation monitoring technology is a new research monitoring technology in China,which can quickly and efficiently monitor the regional electromagnetic radiation environment.We studied the main factors which can influence the monitoring results of drive-test monitoring mode and analyzed the experimental data,the experimental conclusions of each influencing factor are obtained in this paper.Through theoretical analysis,anechoic chamber measurement and actual environment measurement,the calculation and experimental models are established.The calculation results show that when the vehicle traveling speed is in the range of 18 km/h、36 km/h、60 km/h,the impact of vehicle speed on the measurement results can be ignored.The roof reflection on the vehicle has a certain impact on the electromagnetic radiation monitoring system.We can choose a reasonable speed.The different materials can be laid on the roof according to different test conditions.Absorbing materials can reduce the influence of roof reflection on drive-test electromagnetic radiation monitoring system and ensure the accuracy of monitoring data.
