Default Where does the far field start on a phased array?

Hi Dave

I'm curious about two things.

1 - Do you intend to actually make and record measurements of the
radiated field, or do you want to determine the minimum distance at which
the measurements can be made?


yes

2 - What prevents the use of a computer modeling program to predict
the pattern?


nothing. I think that will be done. But a theoetical analysis would be
nice if possible.

Hi Dave

Would you consider building a scale model of this array to allow a polar
orbiting satellite to be the illuminator?
I get some pretty good radiation pattern plots at VHF, using Patrik Tast's
SignalPlotter program and NOAA satellites.
