摘要
介绍了一种基于DDS的连续波雷达模拟源的设计方案。阐述了其工作原理,并详细介绍了组成该模拟源的主要部件的工作原理和技术指标。实践表明,其具有大动态功率输出范围、高频率稳定度和低功耗的特点,连续工作时间长,使用方便灵活。最后推导出了模拟源雷达截面的计算公式。
A design of a CW radar signal simulator based on Direct Digital Synthesizer and its operation principle are described, the operation principle and speeifications of the main parts are introduced. Practice has proved that it has more advantages, such as wide dynamic output range, high steady frequency, low power consumption, long working hours, convenient use and so on. At the end of this paper, the expression to calculate the RCS of signal simulator is provided.
