radar navigation chart的意思|示意

However, both alone has some limitations, in order to enhance the safety of maritime navigation, it is necessary to radar images superimposed display on the electronic navigation chart.

但是两者单独使用有一定的局限性，为了更好的提高海上航行安全，实现雷达图像与电子海图叠加显示是必要的。

The smart displays provide navigation and collision avoidance visualization from the radar sources and are used together with the Electronic Chart Display and Information System-Navy (ECDIS-N).

智能显示器通过雷达信号提供导航服务并接收防撞信息，同时，该显示器还可以与海军电子图显示和信息系统（ECDIS-N）一同使用。

The system not only realizes the display of electronic navigation chart and radar images, but needs to complete the design of the interface, achieve the various functions through the control system.

本设计不仅需要分别实现电子海图和雷达图像的显示内容，而且需要完成整个交互界面的设计，通过控件实现系统的各个功能。
