摘要
通过跟踪国内外频率合成技术的发展现状、趋势及其新理论、新方法,对目前典型的几种频率合成体制,如直接模拟式频率合成技术(DAS)、直接数字式频率合成技术(DDS)和间接锁相式频率合成技术(PLL)分别进行分析、研究,探索其在雷达、通信、电子战等领域的应用需求。
With the development, trend, new theory and solution on frequency synthesizing technolo- gy, some existing typical frequency synthesizing techniques are studied, such as Direct Analog Synthesizing (DAS), Direct Digital Synthesizing (DDS) and indirect Phase-Lock Synthesizing (PLL), and their applications in radar, communication and EW fields are explored also.
