基于DDS的雷达多目标相参回波信号生成方法

A method of generating radar multi-target phase-coherence echo based on DDS

介绍了一种基于DDS的雷达多目标相参回波信号生成方法。通过在特定时刻对DDS生成的信号进行补相,可以使单DDS同时生成多个目标的与被测雷达全相参的常规脉冲和线性调频回波信号。最后给出了仿真结果。

A method of generating radar multi-target phase-coherence echo based on DDS is discussed. By setting the DDS＇s offset phase at given time,a single DDS can generate multi-target phase-coherence signals including LFM and general pulse for evaluated radar. At last,the simulation result is provided.
