一种船用导航雷达回波高分辨显示装置的设计

Design of An Echo Display Equipment with High-resolution of Shipborne Navigation Radar

船用导航雷达数据处理单元采用"现场可编程门阵列(FPGA)+高级RISC微处理器(ARM)"的系统架构,通过FPGA和ARM处理器功能模块合理分配,软件算法优化设计,实现了在嵌入式ARM处理平台上高分辨率的回波显示(1 600×1 200),满足了船用导航雷达的高端需求,还可以裁剪软件模块和修改显示驱动的方式,降低船用导航雷达的显示分辨率,满足小屏幕显示的中低端需求,通用的硬件平台有助于产品的升级和维护。

Through the rea dules for FPGA＋ARM processor and optimized software algo rithm design,this paper realizes high-resolution echo display（1 600 × 1 200） based on embedded ARM platform, satisfies the advanced usage demand of shipborne navigation radar;moreover,which can cut out software module and modify the mode of display driver to reduce the display resolution of shipborne navigation radar,and satisfy the medium/low usage demand of small screen display. Universal hardware platform is helpful for the update and maintenance of products.
