英文摘要： Integration of Radar and Communication（Radcom） is one of important research areas for multi-functional Integrated Radio Frequency Systems(MFIRFS). Most attention are drawn for the Radcom system based on signal-sharing, due to its high integration degree. Based on multi-carrier signal processing, this proposed research is to aim the fundamental issues ,including the scheme of multi-carrier signal-sharing for radar and communication, the method of radar target echo detection based on signal-sharing and the approach to data modulation and its demodulation with signal-sharing as well as the Radcom system performance, and to solve some key technical problems, including the waveform and characteristics of multi-carrier shared signals, detection of radar target and the high-speed synchronization of burst instantaneous communication based on multi-carrier shared signals, and the suppression of the peak to average power ratio, on the basis of linear FM with quasi- orthogonal multi-carrier multiplexing and orthogonal frequency division multiplexing(OFDM).It is to find out the new way of Radcom, striving to lay the solid theoretical and technical foundations for the development of Radcom system.
