Rain

Rain propagation model

Description

Model the behavior of electromagnetic radiation from a point of transmission as it travels through rain[1]by using aRainobject. 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 obstacles.

Creation

创建一个Rainobject by using thepropagationModelfunction.

Properties

expand all

Rain rate, specified as a nonnegative scalar in millimeters per hour (mm/h).

Data Types:double

Polarization tilt angle of the signal, specified as a scalar in degrees.

Data Types:double

Object Functions

pathloss Path loss of radio wave propagation
range Range of radio wave propagation
add 增加传播模型

Examples

collapse all

Display the coverage area for a transmitter in heavy rain. Specify the rain rate as 50 millimeters per hour.

pm = propagationModel("rain","RainRate",50); tx = txsite("Name","Apple Hill","Latitude",42.3001,"Longitude",-71.3604); coverage(tx,pm)
