摘要
阐述了直接数字频率合成（DDS）技术在雷达系统中的应用,重点对DDS的触发抖动引起IQ相位突跳的机理进行了理论分析和实验研究。给出了判别此类问题的实验方法,指出了设计对策。
The application of DDS technology for Radar was described. The IQ phase jumping caused by DDS trigger trembling was studied through theoretical analysis and experiment. At the same time,the method to solve this problem was introduced,and the design method to avoid this defect was pointed out.
