Abstract :
The effect of rain on the field at a point irradiated by a microwave antenna is found, in contrast with previous work, to be effectively independent of the parameters of the antenna. The standard Fresnel zone criterion for the `active rain volume¿ has been extended to treat rain in the near field of the antenna.
