Coherent effects in single scattering and random errors in antenna technology
(2002) In Technical Report LUTEDX/(TEAT-7109)/1-21/(2002) TEAT-7109.- Abstract
- Lack of knowledge prevents us from exactly calculating the behavior of electromagnetic
ﬁelds. We study two extremes in this respect: scattering against
randomly distributed particles (no idea of the position or orientation of the
scatterers), and random errors in antenna technology (small deviations from
what we think are the proper parameters). Random variables are used to
model our lack of knowledge, and far ﬁeld expressions are studied. Using the
concept of characteristic functions from probability theory, results for arbitrary
probability distributions are obtained. We explain an anomaly in the
forward scattering direction in single scattering theory, present... (More) - Lack of knowledge prevents us from exactly calculating the behavior of electromagnetic

forward scattering direction in single scattering theory, present simple formulas
for the directivity, side lobe level, and beam eﬃciency for a general
array antenna with random errors, and a simple formula for the scattering
coeﬃcient from a general frequency selective structure with random errors. (Less)
