phase coherence meaning in English
相位同调性；相位相干性
相位相干性
Examples
- The main contents include polarimetric interferometric phase coherence optimization ( pipco ) ; random volume over ground ( rvog ) coherence scattering model and corresponding inversion model ; optimization of inversion procedure using ga
主要内容包括:极化干涉相干最优理论,相干散射模型和反演模型以及基于遗传算法的参数反演过程。 - The thesis reviews the theory which is the basis of synthetic aperture processing and introduces five algorithms of image reconstruction : the coherent addition provides a good opportunity for the real time sas ; the envelope processing can work when sonar echo returns lack phase coherence ; the i - q processing can reduce the sampling rate ; the broadband and ctfm processing are both aimed to increase the sas mapping rate
讨论了用于重构图象的五种算法，包括简单的可进行实时处理的相关合成法，可以在缺乏相位信息时使用的包络处理法，可以降低采样率、减少运算量、存储量的正交处理法，可以提高声纳运行速度，从而提高成象率的宽带处理法和ctfm法等五种算法。 - The results of the test demonstrated that the system has a good performance in the linearity , dynamic scope , isolation , coherence of the amplitude . the group delay of the upmixers is 2ns , which is better than other domestic manufactures . because the inconsistency between the isolation and the phase coherence , and the error of the test method , we haven ’ t gotten the good performance of the phase coherence . the next work is improving the restrain of the filter to the lo signal and the phase test methods
在单路发射通道上,群时延达到了2ns ,优于国内很多产品。三路通道之间的相位一致性由于测试方法的误差以及隔离度指标的牵引作用,我们不能调试达到非常好的在相位一致性指标,再下一轮的工作中必须提高滤波器对本振信号的抑制度,改进相位测试方法以达到指标要求。
