Thank you David,
After pondering your idea here for the last few hours, I'm thinking you mig=
ht be on the right track. But a few questions arise.
1) Could these phase differences possibly occur on such a minute scale and =
at such a rapid rate that the resulting "flanging" or "wavy" effect is almo=
st imperceptible to most people?
2) Would your explanation accommodate the observable fact that introducing =
boundaries/baffles into the picture almost always stabilizes the image, eli=
minating the effect?
3) Any thoughts on how this anomaly occurs in M-S arrays?
I have some possible tentative answers in mind, but I'd love to know what y=
ou and others would say.
