| Abstract | 为了预估射电天文台址无线电宁静区内电磁干扰源辐射功率，提出了一种开场测试分析与评估方法. 首先选择天气状况良好，干扰源辐射范围之内的开阔场地作为测试地点，获取干扰源和测试接收天线经纬度、高程信息，搭建测试系统测试读取接收功率；其次采用贝塞尔大地投影反解法求得两者之间的大地线长和大地方位角，提取干扰源至测试接收点的剖面高程数据；再次依据地形特征选取电波传播模型预测电波传播损耗；然后计算干扰源和测试接收点在干扰方向的天线增益；最后结合接收功率、传播损耗、特定方向上的天线增益估算干扰源设备的辐射功率. 经实际测试，该方法可以高效、快捷预估干扰源辐射功率，验证了该方法的合理性，相关成果可以为台址频谱管理及宁静区干扰协调提供有力的数据支撑. |
| Other Abstract | In order to estimate the radiation power of electromagnetic interference sources in the radio quiet zone of the radio observatory site, an open field testing analysis and evaluation method is proposed Firstly, select an open area with good weather conditions and radiation range of the interference source as the testing location, obtain the interference source and test the longitude, latitude, and elevation information of the receiving antenna, and build a testing system to test and read the received power, the Bessel geodetic projection inverse method is used to obtain the length of the geodesic line and the positive and negative position angles between the two. Secondly, the profile elevation data from the interference source to the testing receiving point is extracted, Select a suitable radio wave propagation model based on terrain features again to predict radio wave propagation loss, then calculate the antenna gain of the interference source and test receiving point in the interference direction, and finally estimate the radiation power of the interference source equipment by combining the received interference source power, radio wave propagation loss, interference source in a specific direction, and receiving antenna gain After practical testing, this method can efficiently and quickly estimate the radiation power of interference sources, verifying its rationality. The relevant results can provide strong data support for station site spectrum management and quiet area interference coordination. |
