摘　　要：指令线以无线电磁波作为传输媒介,其可靠性、隐蔽性和有效性是指令系统研究的重点。分析了指令线的典型干扰模式,重点研究在复杂战场环境下如何利用频域、时域、码域等各种资源提高指令线的抗干扰能力,并针对典型的指令线抗干扰措施进行了仿真分析,仿真结果用于为复杂环境下武器系统指令线设计提供参考。Commandline adopts radio electromagnetic wave as transmitting medium, and its reliability, concealment and validity are the research emphases in command systems. The typical commandline interference patterns are analyzed, and how to improve anti-interference ability by frequencydomain, timedomain and codedomain resources in complex battlefield environment is specially studied. The typical commandline anti-interference methods are simulated, and the results can be used as references for weap- on system commandline design in complex environment.
