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.
