摘要
该文介绍了等幅报的信号特征,分析了等幅报的设计方法和硬件实现,基于CPCI总线、高性能FPGA、DAC、DDS、PLL等构建的硬件平台,实现了可叠加多种干扰信号的等幅报信号的射频调制发射,可以满足部分场景下对可编辑、可重复、叠加干扰参数可控的等幅报信号的需求,具有一定的应用价值。
This paper introduces the signal characteristics of the CW signal,analyses the design method and hardware implementation of the CW signal.Based on CPCI bus,high-performance FPGA,DAC,DDS,PLL and other platforms,the radio frequency modulation and transmission of the CW signal with multiple interference signals can be realized,which can meet the needs of editable,repeatable and overlapping interference signal parameters controllable in some scenarios.It has certain application value.
