NEW CONCEPTS AND TECHNOLOGIES IN T/R MODULE DEVELOPMENT FOR ACTIVE PHASED ARRAY RADAR AND SAR APPLICATIONS

摘要

This paper describes the status and trends of T/R module technology for earth observation high resolution synthetic aperture radar applications at EADS Deutschland GmbH (European Aeronautic Defence and Space Company, Germany), formerly DaimlerChrysler Aerospace AG. T/R modules are the key elements of active phased array antennas. In the field of earth observation two main T/R module architectures are applied to fulfil the need for switchable polarisation, as well as to meet the full polarimetric requirement, i.e. simultaneous reception of two differently polarised RF signal parts. Besides existing T/R modules, designed and manufactured within different programs, technological trends for T/R modules and monolithic microwave integrated circuits, digital control electronics, as well as novel package concepts will be presented.
