myproject name is SHAPPED PATTERNS FROM A CONTINUOUS PLANAR DISTRIBUTION.
Abstract: A pattern synthesis procedure is developed
for a planar aperture with a circular boundary.
A &symmetric continuous distribution is
assumed and required to produce a flat-topped
beam with controlled ripple, surrounded by ring
side lobes of controlled height. With M filled-in
nulls in the shaped region, there are 2* solutions
for the aperture distribution. Sampling can yield
the excitation of a circular grid planar array.
Linear stretching extends the results to an elliptical boundary.
