摘　　要：针对某型装备电视测角仪训练成本高、训练损耗大的现状,利用FPGA技术设计某型装备电视测角仪视频信号发生装置以代替测角仪,介绍了测角仪的视频显示方式和CCIR制全电视信号产生原理,将视频信号分解为同步信号,消隐信号,图像信号;以行计数器和列计数器构成视频图像的时间基准,通过对行、列计数器编码实现对视频中图像信息的模拟与控制,使用RS232总线与上位机通信以控制不同视频图像的切换。for a certain type of equipment TV angle meter high training costs, and tigh loss of status, use FPGA technology to design a TV goniometer video signal generator in place of goniometer, this article describes the goniometer video display principle and CCIR composite video, the video signal is decomposed into sync signal, blanking signal, the image signal. With the good counter and time reference of row counter constitution video image, through realizes to line and row of counter codes to the simulation and control of video, using RS232 bus to communicate with the host computer to control different video switching.
