摘  要:综合射频系统集雷达探测、数据通信和电子干扰等多种功能为一体,显著提升武器平台在复杂战场环境下的生存能力和作战效能,是武器装备的重点发展方向。针对现有综合射频技术难以高效同时实现多功能等不足,提出构建基于多输入多输出(multi-input-multi-output,MIMO)阵列的综合射频系统。研究结果表明,通过充分利用MIMO阵列的空间自由度和波形自由度,基于MIMO阵列的综合射频系统能够同时实现多功能。将系统探测通信性能、反侦察抗干扰能力、兼容性等方面与传统综合射频技术进行对比,表明基于MIMO阵列的综合射频系统具有独特优势。对基于MIMO阵列的综合射频系统关键技术进行了梳理分析和展望。Multifunction radio frequency(MFRF)systems support multiple functions inclu­ding radar detection,data communications and jamming.Thus,MFRF systems can obvious­ly enhance the survivability and the effectiveness of weapon systems in complex battlefield en­vironments,and represent an important development tendency of military equipment.This study proposed an MFRF system based on MIMO array(MIMO-MFRF),which could over­come the limitations of existing systems such as the low efficiency of supporting multiple functions etc.Analysis showed that by exploiting the spatial and waveform diversity of MIMO systems,MIMO-MFRF systems provided multiple functions simultaneously.Then all of the detection and communication performance,the capability of anti-reconnaissance and suppressing interference,and the compatibility of the MIMO-MFRF were compared with those of the conventional MFRF system,which demonstrated special superiority of the MIMO-MFRF system.Finally,the key techniques of MIMO-MFRF systems were analyzed.This study should be a refenence for developing next-generation MFRF systems.
