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 e nv ironment. No matter what measures of clutter suppression are adopted in signal p rocessing, radar engineers discover there are more or less false plots in the st age of radar data processing. So it is necessary to research for anti-clutter m ethods in the stage of radar data processing. This paper proposes some effective methods in the stage of data processing including echo pretreatment, correlatio n filter, radar control and radar display control.
