Kurzbeschreibung
This easy-to-read volume explains the principles of array and phased array antennas at an introductory level, without relying heavily on a thorough understanding of electromagnetics or even antenna theory. Although the principles are explained mathematically, the introduction is based on the array's physical characteristics rather than mathematics.
