aperture time meaning in Chinese

穿孔时间
空隙时间
孔径时间
口径时间

This is related to certain physical limitations of the image sensors , such as finite cell area and finite aperture time
这一点与图像传感器(如：有限栅格区和有限过孔时间)的一定的物理限制条件有关。
( 1 ) . here we build the system space geometry model : the transmitter and receiver fly on different platforms and at different height , two flight paths are unparallel . based on the chirp signal and the taylor series , we analyze the range history and synthetic aperture time , then demonstrate the equation of the azimuth resolution about air - born bistatic spotlight synthetic aperture radar , meanwhile we obtain the equations of doppler bandwidth and doppler frequency modulate rate
本文以机载聚束式合成孔径雷达成像作为研究背景,主要完成了以下几方面的工作: ( 1 )建立了一种机载双站聚束式sar空间几何数学模型,对方位分辨力进行了理论分析,进行了数值分析与仿真,讨论了不同条件对双站聚束模式sar系统分辨力的影响。
