基于DSP+DUC的短波阵列信号发生器

Design of an HF Array Signals Generator Using DSP+DUC

为了在实验室中获得短波天线阵列信号,应用DSP芯片和DUC芯片(数字上变频器)设计了一个实用电路短波阵列信号发生器,模拟实现了短波九元天线阵的多种阵型、不同来波方向及存在同频多信号时的阵列输出信号。

To obtain the high frequency (HF) array signals,an applied circuit called HF array signals generator is designed using DSP and DUC(Digital Up Converter).The generator simulates the generation of output signals of 9-element arrays with different array format,different direction of arrival (DOA) and existing cochannel signals respectively.
