高频地波舰载OTH雷达信号产生器研究

摘要

Based on the analyses for the generator methods of LFM signal and the development for the signal generator of HF ground-wave shipboard OTH radar, a s ignalgenerating method with the computer-controlling direct digital synthesis techni q ue is presented. LFM and m order signal generator are designed wit h the method　according to the technique requirements of radar system, and the testing results are given.%基于LFM信号产生方法的分析和高频地波舰载OTH雷达信号产生器研制，提出了一种 计算机控制的直接数字合成信号产生方法。根据雷达系统的技术要求用该方法设计了LFM和 m序列信号产生器, 并给出了实验测试结果。
