6.1    Introduction

An electronically scanned array (ESA) provides a significant advantage over its predecessors (passive arrays and reflector antennas) via beam agility. Phase shifters at each radiator element of an ESA provide the capability of rapidly scanning the array beam on the order of microseconds. The ability to accurately command array ...
