摘要
介绍一种基于DDS芯片AD9854的雷达中频目标模拟器,以ADSP-BF532处理器为核心,以AD9854ASQ频率合成芯片为基本目标信号产生器,产生一组和、差模拟中频回波信号,可产生常规脉冲、相位编码、线性调频等多种不同调制方式的雷达中频回波,输出一组和、差两路模拟中频回波信号,可用于多种新体制跟踪雷达的调试和训练。
A radar intermediate frequency simulator based on DDS chip AD9854 is introduced. The simulator uses the ADSP-BF532 processor as the core, the ADgS54ASQ frequency synthesis chip as target signal generator, and generates a group of analog intermediate frequency echo. The simulator can produce different modulation modes of radar intermediate fre- quency echo, such as general pulse, phase coding and LFM, and output a team of adder, subtract return wave. It can be applied to debugging and training of multi-kinds of new system tracking radar.
