中文摘要 |
通过比对测试和理论计算,对多普勒甚高频全向信标/测距仪(DVOR/DME)进行电磁辐射环境影响评价。结果显示,在以该设备的发射天线轴线为中心、半径100—1000m、距地面高度1.7—20m的区域内。电磁辐射强度不会大于8.5×10-2V/m,表明采用DVOR/DME的民航导航台不会对其周围的环境以及居民健康造成明显的电磁辐射危害。 |
英文摘要 |
Based on an analogic survey and a theoretical calculation, an environmental assessment impact of the electromagnetic fields (EMF) of a Doppler very high frequence omnirange/distance measuring equipment (DVOR/DME) to be extensively applied in China has been conducted. The results show that the field intensities were below 8.5×10-2V/m at an altitude of 1.7—20 m above the ground within an area of a 1000 m radius centred on the antenna of a DVOR/DME, indicating that the low level of EMF from a DVOR/DME used in the guide station of civil aviation would not cause a health hazard among the local residents. |
