摘　　要：联合战术信息分发系统(JTIDS)是美军为适应联合作战而研制的综合通信、导航、识别系统。首先分析了JTIDS的通信体系结构、消息格式和抗干扰等特性,接着对JTIDS的传输误码率进行了仿真,最后参照ITU-R SM.1046建议的频谱使用效率分析方法,对3种通信模式、4种典型时隙封装格式下的JTIDS频谱使用效率进行了比较分析。Joint tactical information distribution system(JTIDS)is an integrated system of commu-nication,navigation and identification developed by U.S.Military for suiting the combined opera-tions.Firstly,the characteristics of communication system’s framework,information format and anti-jamming capability,etc.of JTIDS are analyzed,then the transmission bit error rate(BER)of JTIDS is simulated,finally,referring to the spectrum utilization efficiency analysis method recom-mended by ITU-R SM.1046,the spectrum utilization efficiencies of JTIDS under three communica-tion modes and four typical time slot encapsulation formats are compared and analyzed.
