Rain propagation model
Model the behavior of electromagnetic radiation from a point of transmission as it
travels through rain  by using a
object. Propagation models for rain are valid from 1 to 1000 GHz, assume line-of-sight (LOS)
conditions, and disregard terrain, the curvature of the Earth, and other
Rain object by using the
RainRate— Rain rate
16(default) | nonnegative scalar
Rain rate, specified as a nonnegative scalar in millimeters per hour (mm/h).
Tilt— Polarization tilt angle of signal
0(default) | scalar
Polarization tilt angle of the signal, specified as a scalar in degrees.
Display the coverage area for a transmitter in heavy rain. Specify the rain rate as 50 millimeters per hour.
