One-way radar propagation factor

calculates the one-way propagation factor assuming a surface target and a sea state of
`F`

= radarpropfactor(`R`

,`freq`

,`ANHT`

)`0`

. The calculation estimates the complex relative permittivity
(dielectric constant) of the reflecting surface using a sea water model described in [1]
that is valid from `100`

MHz to `10`

GHz. The target
height is assumed to be the height of significant clutter sources above the average surface
height. Specifically, the target height is calculated as `3`

times the
standard deviation of the surface height. Assuming the paths are the same, the two-way
propagation factor is 2`F`

.

allows you to specify additional input parameters as Name-Value arguments. You can specify
additional name-value pair arguments in any order as
`F`

= radarpropfactor(___,`Name,Value`

)`Name1`

,`Value1`

,...,`NameN`

,`ValueN`

.
This syntax can use any of the input arguments in the previous syntax.

`radarpropfactor(___)`

plots the one-way propagation
factor in dB versus range in km. Default range units are km.
