雷达通信一体化共享信号技术研究

Study of Signal Sharing Technologies for Integration of Radar and Communication Systems

雷达通信一体化是多功能综合射频系统的一个重要的研究方向,基于信号共享的雷达通信一体化系统因其一体化程度最高而备受关注.针对雷达通信一体化信号设计中存在的不兼容和互干扰问题,对基于频分多载波Chirp技术、正交频分复用技术(OFDM)和扩频技术的雷达通信信号共享的可行性和方案进行了研究,并对共享信号雷达目标回波检测方法、共享信号数据调制解调方法以及雷达通信一体化系统性能等方面的基础性问题进行了初步分析.

Integration of Radar and Communication （Radcom） systems is one of the important research areas in multi-functional integrated radio frequency systems （MFIRFS）. More attentions are paid to the integration of Radcom systems based on signal sharing, due to its maximum degree of integration. Considering that there exists some problems of signals being not compatible and having mutual interference in the signal design for the integration of Radcom systems, this paper studys the feasibility and its scheme of Radcom signal sharing based on the techniques of frequency division multi-carrier chirp signal, orthogonal frequency division multiplexing （OFDM） and spread spectrum, and makes an introductory analysis of detection of radar target echoes and demodulation of data with signal sharing, and certain basic problems of performance on integration of Radcom systems and others.
