ABSTRACT x LR 2H>B}  
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 x LR 2H>B}  
be addressed. In order to describe the needs for scanned array development, this book begins x LR 2H>B}  
with a brief discussion of the history that led to present array antennas. This text is a compact x LR 2H>B}  
but comprehensive treatment of the scanned array, from the underlying basis for array pattern x LR 2H>B}  
behavior to the engineering choices leading to successful design. x LR 2H>B}  
The book describes the scanned array in terms of radiation from apertures and wire x LR 2H>B}  
antennas and introduces the effects resulting directly from scanning, including beam broad-ening, impedance mismatch and gain reduction and pattern squint and those effects of array x LR 2H>B}  
periodicity including grating and quantization lobes and array blindness. x LR 2H>B}  
The text also presents the engineering tools for improving pattern control and array x LR 2H>B}  
efficiency including lattice selection, subarrray technology and pattern synthesis. Equations and x LR 2H>B}  
figurers quantify the phenomena being described and provide the reader with the tools to trade-off various performance features. The discussions proceed beyond the introductory material and x LR 2H>B}  
to the state of the art in modern array design. x LR 2H>B}
