摘要
文章介绍了一种基于直接数字合成(DDS)技术,利用CPLD芯片和其它外围电路生成测试设备所需的雷达视频模拟信号和其它信号的硬件实现方案并给出部分仿真结果。该项设计通过数字控制可以灵活的模拟不同特性目标回波信号,并提供其它激励信号,具有良好的可编程性。
The realization technique of video signals by CPLD based on DDS is introduced,which is used to testing some radars.The system can simulate the echo signals with different characteristic and supply other drive signals controlled by data bus easily. At last, some result gotten by simulation is shown in the paper.
