The purpose of the antenna array is to serve radar, electronic support measure and electronics, electronic warfare and communications functions. Implicit in the multisystem function array is the need to operate many of these systems simultaneously. Additionally the array should be capable of controlling fundamental radiation characteristics such as beamwidth, beam size, sidelobe levels and radiat ...

Satellite communications, Airborne radar, EW, and Communications systems differ significantly in their antenna requirements. Not only do the various systems differ in their primary functions, but the many variations within one system will affect antenna requirements. For example, an airborne radar system may be configured functionally as a tracking, search and track, altimeter, navigation, groun ...

For tactical communication systems parabolic antennas can acquire a single satellite but requires complex mechanical structure and control systems. For multiple satellite links, separate antennas are necessary. This consumes valuable area on the ship, and requires more hardware and resources. With the availability of a mature monolithic microwave based Transmit/Receive modules it is now possibl ...

The replacement of millimeter-wave traveling wave tube by solid-state power amplifiers has been recognised as a very important goal for some time. Solid-state power amplifiers provide the substantial benefits of elimination of high voltage supplies,reduction in size and weight, and generally improved reliability, especially for airborne microwave systems. Hoever, the demans of higher power at high ...

Electronically steered arrays are becoming increasingly important to meet performance and cost requirements of modern radar and communications systems. Key to successful implementation of these arrays is the availability of low cost, high performance components that are both lightweight and small. This proposal presents a unique microwave frequency phase shifter and the construction technology t ...

The use of electronically steered array is necessary to meet performance requirements of modern airborne radar and communications systems. Phase shifters are critical components in such arrays and often become the performance limiting component of thesystem. A substantial reduction of the the DC power consumption for spaceborne, airborne and portable sysytems is a very important consideration. Ver ...
