摘要
微型飞行器潜在的应用前景和使用价值,使其在较短的时间内就吸引了许
多研究者的注意,并很快成为当今国际上一个新的研究热点。微型飞行器上所
获取的视频数据及飞行器飞行参数等需要通过下行线路传送到地面控制站中进

键技术。
根据课题的来源和要求,本文为微型飞行器的地面显控任务提供了一个以
DSP 和 FPGA 为核心的复合信号实时处理系统。文章论证了以 TS203 DSP 为核
心的地面显示控制系统总体方案,探讨了地面站系统的工作原理和流程,对该

了说明。其中 DSP 的合理应用保证了图像处理和传输过程的实时性,FPGA 的
使用也极大地提高了系统的集成度和灵活性。同时,本文在软件方面研究了图
像显示的反走样算法,并对此地面站系统进行了程序设计与优化。
该系统高集成度的硬件电路设计和经过优化的程序,有效地保证了地面站
系统对下行信号数据的实时处理与可靠显示。

Abstract
Recently the potential and promising prospect of Micro Aerial Vehicle (MAV)
in application has e a hot topic worldwide and attracted attention of many
researchers. The data of videos as well as flight parameters of the aerial vehicles is
collected, processed and displayed after being transferred via downlink channel to
the ground control station. Thus the ground control and display system is among the
most important devices of MAV. Transmission, processing and displaying of the
video images has e one of the critical technologies for MAV research.
In this thesis, posite real-time signal processing system based on DSP and
FPGA is presented for MAV ground control. The reason of basing the system on
TS203 DSP is addressed and the principle of the work flow is presented. The design
details of the hardware, the features and functions of chips used in the system are
specified: DSP is reasonably facilitated to ensure the real-time property of image
processing and transmission; FPGA is used to enhance the integrity and the
flexibility of the system. Meanwhile, the anti-aliasing arithmetic of rotating graphics
is explored for software design and optimization.
The design of high-density integrated circuit and the optimized programming
part ensure the real-time property and the reliability of pro
