Wideband digital phased array radar is a promising technology to monitor ocean environment. It can realize wide sea area, multi targets and high precision sea area monitoring. The key component of wideband digital phased array radar is digital RF transceiver chips. This paper briefly introduces the development and technology of integrated digital RF transceiver chips. In this paper, we discuss and analyze several key technical problems. The analysis results suggest that broadband digital phased array radar could be the best candidate for the next generation ocean surveillance.
