Research On Multi-channel Broadband Radar Receiver

With the development of science and technology, as well as the rivalries in modern battlefield, it demands radar to provide more advanced functions. Receiver, as one of the most important components in radar system, needs to be more sophisticated, such as multi-channel reception , high resolution by Broadband processing, high integration , high reliability and robustness in ECCM. Receiving system is composed of RF front-end, precise frequency synthesizer, digital IF sampling and etc. Several key techniques have been studied in this thesis. Achievements this paper has concluded are useful during the design of new type radar. All technical and tactic performances can be improved.The application of new materials and design methods has greatly enhanced the performances of receiving subsystem. The emergence of mini-devices makes compact integration become possible. Wideband processing for high resolution radar is possible by means of digitalization technique.As basic design techniques of receiving system, they can be applied in different kinds of radar, such as anti active interference radar, land based or sea based phased array radar. Of course, they can be used in ECCM and communication area.
