Scanning arrays present the radar or communications engineer with
the ultimate in antenna flexibility. They also present a multitude
of new opportunities and new challenges that need to be addressed.
In order to describe the needs for scanned array development, this
book begins with a brief discussion of the history that led to
present array antennas. This text is a compact but comprehensive
treatment of the scanned array, from the underlying basis for array
pattern behavior to the engineering choices leading to successful
design. The book describes the scanned array in terms of radiation
from apertures and wire antennas and introduces the effects
resulting directly from scanning, including beam broadening,
impedance mismatch and gain reduction and pattern squint and those
effects of array periodicity including grating and quantization
lobes and array blindness. The text also presents the engineering
tools for improving pattern control and array efficiency including
lattice selection, subarrray technology and pattern synthesis.
Equations and figurers quantify the phenomena being described and
provide the reader with the tools to tradeoff various performance
features. The discussions proceed beyond the introductory material
and to the state of the art in modern array design. Contents: Basic
Principles and Applications of Array Antennas / Element Coupling
Effects in Array Antennas / Array Pattern Synthesis / Subarray
Techniques for Limited Field of View and Wide Band Applications
