coherent video meaning in English

相干视频信号
相干影像

In the paper , a coherent video signal simulation is applied to model and simulate a pulse doppler radar seeker
本文采用相干视频信号仿真方法对脉冲多普勒雷达导引头进行了建模和仿真研究。
In order to simulate the return , a radar coherent video echo model is used to simulate target echo , clutter and noise separately . then the three parts which are in the same range cell are added together to form a matrix to represent return in one radar coherent processing interval ( cpi ) . this matrix is called a frame of range doppler data
为了较为全面地对雷达回波进行仿真,采用相干视频回波模型分别模拟雷达目标回波、杂波和噪声,通过在距离单元内叠加的方法,将一个雷达相干处理周期内的回波数据用一帧距离多普勒平面数据表示。
