T/R modules for active phased array radars

This paper presents a summary of the three T/R modules developed for weather active phased array radars. Critical factors that influence the system performance are discussed in terms of the technology and tradeoffs that includes cost. Performance is considered for deployable dual-polarized PAR radar systems. The three T/R modules and antenna aperture Line Replacement Units (LRU) have been designed, integrated and tested. Performance and cost are derived from affordability constraints imposed by the latest technology is presented.
