摘要
针对直接数字频率合成器(DDS)AD9858的特点及工作模式,提出了一种通过计算机并口控制AD9858的雷达信号波形产生器,可模拟产生高性能多波形复杂雷达发射源信号,该雷达信号波形发生器输出信号频率、相位、幅度可调,结构简单。
Aiming at the feacutres and operation modes of DDS AD9858,a radar signal waveform generator based on the AD9858 that is controlled by computer through the parallel port is designed. Complex radar transmitting signals with multiple waveforms and high performance could be generated simulatively by the generator whose output signals can be programmed on the frequency, phase and amplitude, and the structure of the generator is very sample.
