Uniform polar distance is a distribution function designed to define a random positioning of transmitter along the
radius of coverage cell R (i.e. all the points are distributed over a circular area defined by max distance with the
same probability), to achieve a random uniform distribution of transmitters within a circular area centred around a given
zero-point.
This function has one parameter - max distance - and the uniform polar distance distribution is typically used for
deriving distance factor used in calculation of the relative locations of transceivers within a link and between victim
and interfering links. The result of the trial on such a distribution, the distance factor, is then multiplied by a
coverage radius or simulation radius. Hence the default maximum value of R is set to 1, meaning that after multiplication
of this random factor with the radius value, the resulting distance will be distributed uniformly along the entire
coverage/simulation radius.
Note that this is equivalent to defining a uniform density of transmitters on a circular area together with uniform
polar angle (with 360 deg) or uniform distribution in the angle domain (0,360 deg).
