Abstract

It is shown that, for certain combinations of frequency and polarisation, the difference in microwave attenuation between two frequencies along a terrestrial link can give a much better estimate of path-averaged rain rate than can be obtained from a single frequency. An example is given which shows that attenuation difference can successfully provide rainfall estimates in practical applications
