| Summary: | The invention discloses a method for measuring transmission loss of a large truss antenna housing, and belongs to the field of large truss antenna housings. The method comprises the following steps: firstly, under the condition that an antenna is not provided with a housing, respectively measuring noise power of the antenna pointing to a radio power supply and nearby cold air by using a spectrum analyzer; and then, installing the antenna housing, respectively measuring the noise power of the antenna pointing to the radio power supply and the nearby cold air by using the spectrum analyzer under the condition that the antenna is provided with the housing, and calculating the transmission loss of the large truss antenna housing according to the measured noise power. The method is simple and feasible, and has popularization and application values.
本发明公开了一种测量大型桁架天线罩传输损耗的方法，属于大型桁架天线罩领域。本发明首先在天线不带罩情况下，用频谱分析仪分别测量天线指向射电源及其附近冷空的噪声功率；然后，安装天线罩，在天线带罩情况下，用频谱分析仪分别测量天线指向射电源及其附近冷空的噪声功率，由测量的噪声功率计算大型桁架天线罩的传输损耗。本发明的方法简单可行，具有推广和应 |
