微波链路非常适合城市环境，因为有许多合适的、不受破坏的位置可以连接接收器和发射器。由于中间水滴的散射和吸收，沿链路发送的信号被接收时功率降低。因此，功率损耗的测量可以转化为总路径降雨量的测量。本文讨论了估算过程准确的要求。本文介绍了使用单频的结果以及双频链路的改进结果。介绍了微波链路未来的潜在应用。
Microwave links are ideally suited to the urban environment, since there are many suitable vandal-free locations to which the receiver and transmitter can be attached. A signal sent along a link is received with reduced power as a consequence of scattering and absorption by intervening water droplets. Thus a measurement of the power loss can be transformed into a measure of total path rainfall. This paper discusses the requirements for the estimation process to be accurate. The paper presents results using a single frequency, together with the improved results from a dual-frequency link. Potential future applications of microwave links are presented.
