在给定设备电气参数的情况下要保证通路中最小的噪音功率,或者在给定噪音功率的情况下要求最小的电气参数值,都需要进行大量工作来选择微波中继站的最佳站距[1、2、3]。 文章[1、3]中确定最佳站距Rопт时是假设Rопт的值小到信号的衰落可以忽略,而文章[2]中却考虑了统计衰落。但是这些著作都没有考虑在地面上安置无线电中继设备的技术设施或容器时因站距R产生的损耗关系和天馈线系统中的非线性转移噪音。
A minimum amount of noise power in the path, given the electrical parameters of the device, or the minimum electrical parameter values required for a given noise power, requires extensive work to choose the best station distance [1 , 2,3]. In [1, 3] to determine the optimal station from R опт is the assumption that R о п т small value of the signal can be ignored, but article [2] has considered the statistical fading. However, none of these works take into account the loss due to the station-station distance R and the non-linear transfer noise in the antenna feeder system when installing the technical facilities or containers of radio relay equipment on the ground.
