System Applications of Microwaves to Radars: Modern Trends

The impact of the microwave technology on the performance of modern radar systems is outlined, together with the resulting design implications. The most advanced characteristics of the main microwave components are pointed out and proper use of combined technologies in complex subsystems as electronically scanned antennas, is shown to be essential in order to reach advanced performance and capabilities for new radars. Different types of antennas configuration are examined from the viewpoint of improvements required by the enhancement of radar characteristics. Similar considerations apply to other microwave radar subsystems. High degree of integration, use of advanced computer resource and techniques are shown to be fundamental in the design and development of advanced microwave components. Outstanding features of advanced radars, as 3D and multifunctional systems, are pointed out. The introduction of new capabilities envisaged or being introduced in radar systems has a deep impact on the requirements for microwave components. On the other hand, technological advancements, mainly in the area of Ga As technology, will make the achievements of these advanced performances more feasible.
