摘要随着科技发展的日新月异，对船舶雷达的要求越来越高，例如如何进一步提高雷达处理杂波的能力，或者如何能够使雷达在恶劣环境中仍然能最大程度上精确地做到航迹跟踪等。利用嵌入式系统可达到较低成本、减小体积的目的，提高系统的可靠性和灵活性，进而更好的实现船舶导航雷达的目标跟踪功能。73349

本次的设计为基于嵌入式终端的船舶目标跟踪，首先介绍了几种目标跟踪模型，如匀速模型、匀加速模型等。其次介绍了几种滤波算法，其中在本次设计中主要使用到的是α-β滤波算法。雷达显控终端的设计则分为硬件设计部分和软件设计部分。搭建好嵌入式开发环境后，开发基于Qt的雷达显控终端，实现了多个模块的功能。最后进行实机测试，最终得到完整的课题设计。

Title   Design of embedded terminal for ship navigation radar。                                                   

Abstract With the development of science and technology,the demand of the ships’radar is increasing。 Such as how to enhance the ability of handling the radar clutter,or how to exactly do the ship trajectory tracking to the greatest extent in the harsh environment and so on。 Embedded systems can be used to lower the cost and volume, enhance the flexibility and reliability of the entire system, in order to better achieve the goals of marine radar tracking。

The design for ship target tracking is based on embedded terminal。 Firstly, several target tracking models are introduced。 Such as CV model, CT model, etc。Secondly, several filter algorithms are introduced。 α-βfilter algorithm is mainly adopted in this design。The design of radar display and control terminal is separated into two part: hardware design and software design。Since the embedded development environment has been built,as long as the radar display and control terminal which is based on Qt system has been established,a number of functions are completed。Ultimatly,if the machine test can be done successfully,the design of radar ship navigation system is achieved。
