Solid-State Upgrade for the COBRA JUDY S-Band Phased Array Radar

COBRA JUDY S-band is a phased-array data collection radar permanently mounted aboard the USNS Observation Island Designed in 1976 and first made operational in 1981, the transmitter hardware has become difficult to support and, in some cases, is entirely obsolete. In December 2004, DTI was awarded a contract to modernize the transmitter by replacing obsolete components with solid-state technology. In this paper, DTI will present an overview of the transmitter design, key technical drivers, and a summary of progress thorough installation of the transmitter in early 2006
