Thanks to Dr. H. Paul Shuch and Stephen
A. Zarkos, the BASIC simulation of the
Fresnel Zone Plate Antennas with Groundplane
will soon be posted to the SETI League


This write-up includes the BASIC program,
some documentation and run-time benchmarks.
It includes how to change the program to
scan frequency instead of bearing ( degrees ).

ALSO INCLUDED, which was NOT included
in the versions I emailed out, is the actual
beampattern which this simulation produces,
of the 40-foot diameter R=ten meter, nine-ring
