Understanding Interference Effect in communication systems.

舰载雷达所处的环境杂波现象比较严重。雷达工程人员发现，无论信号处理采用哪些反杂措施，雷达数据 处理阶段总是或多或少地存在虚假点迹。因此，有必要研究如何在数据处理阶段进一步消除杂波干扰。文中分别就数据 处理的预处理模块、相关滤波模块、雷达控制模块以及雷达显示控制提出了有效的方法。(Shipborne radars operate in a severe clutter environment．No matter what measures of clutter suppression are a— dopted in signal processing，radar engineers discover there are more or less false plots in the stage of radar data processing．So it is necessary,to research for anti—clutter methods in the stage of radar data processing．This paper proposes some effective methods in the stage of data processing including echo pretreatment，correlation filter，radar control and radar display contro1．)
