Phased array antennas can be electronically steered and do not have moving parts, making them an efficient and cost-effective solution for today's complex radar and communications systems. This newly revised edition of the Artech House classic, Phased Array Antenna Handbook, offers the most up-to-date and broadest view of array antennas and systems. Professionals find complete design details that allow them to build and evaluate an array system with speed and confidence. The second edition offers a wealth of critical new material, including a detailed treatment of antenna system noise, sections on antenna pattern synthesis, cutting-edge developments in subarray technology, and in-depth information on array architecture and components.
