Multifunctional Adaptive Microwave Circuits and Systems is a
state-of-the-art survey on Multi-functional, Adaptive Radio Radar and
Sensor, or MARRS, systems and summarizes the findings of a five year
project entitled MARRS: Multifunctional Adaptive Radio Radar and Sensors
that ran from 2001 to 2006. The book presents a systematic approach to
the system level design required to develop MARRS technology.
Developments of the most viable tunable and reconfigurable components
are described. These are Micro Electro-Mechanical System (MEMS) switches
and varactors. The book describes electrically-tunable varactors made
from ferroelectric materials. Applications in tunable switches, tunable
filters, tunable matching networks, and tunable antennas are presented.
Concepts and architectures for RF transmitters designed to optimize
performance by adapting to variable loads, power levels, and linearity
require-ments are explored, as well as reconfigurable and tunable RF
filters using both semiconductor and ferroelectric varactors. The book
also discusses retro-directive antenna arrays, Finally, a multifunction
radar, communication and radiometry system that utilizes a
retro-directive antenna array is described.
