This paper expounds the necessity of integrated Radio Frequency(RF) sensors in network centric warfare from the concept of operations, the restrictions of airborne platform, the development of architecture and the promotion of technology in recent years. The integrated radio frequency system characteristics are analyzed based on the ability of future combat pattern, and the basic architecture of radio frequency integrated solutions is proposed based on a comprehensive design of discrete heterogeneous sensors. Finally, the key technologies of integrated RF system, conformal aperture and RF management are analyzed from the perspective of airborne integrated system, which provides support for design of integrated RF sensors.
