Dear GRASS community,
I would like to simulate the strength of a signal emitted from an
antenna and received by a receiver.
As a first approach r.los gives a good start. Anyway, more accurate
results could be obtained by taking obstruction in the first Fresnel
Zone into account. Finally, having a way to calculate the impact on
indirect paths/reflections, should lead to a reasonably accurate signal
strength map.
Did anybody work on some of these issues, possibly in combination with
GRASS? Is there a good starting point for the calculation of the
obstruction within the first Fresnel Zone.
I don't really understand what you are speaking about (i.e. am
completely incompetent in this field), but would v.net.visibility be
something for you ?
