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.
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。
In this thesis we propose an alternative method to increase the axial resolution of OCT by combining coherence gating with superresolution through an appropriate phase filter.
本文提出一种将光学超分辨术与OCT相干门有机结合的方法来提高OCT的轴向分辨率。
