摘　　要：主要研究船舶交通管理系统(VTS)中雷达原始视频信息的采集。该系统将原始雷达视频信号进行高速A/D变换,根据量化值的范围对雷达视频、方位和触发信号进行调理解调,将调理后的雷达视频与相对应的方位信号实时送给光模块和PCI-Express总线,通过PCI-Express总线将上述信号传输至计算机内存中作实时的雷达信号处理。The collection of original radar video information in the Vessel Traffic Management System （VTS） is mostly studied. The original radar video signals are processed through the high- speed A/D converters, the radar video, azimuth and trigger signals are demodulated according to the range of the quantized values, and then the processed radar video and azimuth signals are real-timely sent to the optical module and the PCI-Express bus, through which the signals above are transmitted to the memory of the computer for real-time radar signal processing.
