【摘要】 船(艇)载航行数据记录仪(Voyage Data Recorder缩写VDR)能够在潜艇和水面舰艇的日常训练和实际作战中实时记录舰艇和艇员的各种实际工作数据以便于事后进行分析研究。 在各种记录数据中,雷达图像数据至关重要,它是船(艇)周围环境的真实再现。雷达图像采集压缩系统可以实时记录船(艇)雷达系统的信号输出。通过地面回放设备的回放,实现舰艇事故前的雷达图像重现,为分析事故原因提供第一手资料。 本课题以船(艇)载航行数据记录仪中的舰艇雷达图像采集压缩系统为研究对象,设计并实现了基于DSP的PCI接口的高可靠性的实时雷达图像采集压缩卡。 本文首先介绍了视频信号和视频接口;接着具体介绍采集压缩卡的硬件设计方法和硬件接口逻辑的设计方法;然后介绍采集压缩系统DSP软件部分,重点介绍实时微内核DSP/BIOS和JPEG2000算法的DSP实现。最后介绍了该PCI采集压缩卡VxWorks下的驱动实现。

【Abstract】 Voyage Data Recorder is an intelligent equipment which is used to record and conserve the important information and parameter of vessel during its voyaging.In all recorded data, radar image data is very important. It can replay the whole environment around the vessel. Radar image capture and compression system can record the realtime radar image data during voyaging and supply the first real data of the accident.This research subject is radar image capture compression recording system of Voyage Data Recorder. The research task is design and realization of radar image capture compression PCI card.This thesis introduces some kinds of video signal and video format. Then gives the design of the radar image capture compression card in point of hardware, including the hardware interface logic design. And gives ways of the software design of DSP. Emphasis is placed on the realtime micro kernel with DSP and the applying of JPEG2000 compression algorithms. And then introduce the driver program of the radar image capture compression PCI card under VxWorks.
