这个技巧通常在风窗的边缘执行，因为它要求一个合适的速度。
This trick is usually performed away from the wind window edges, because a certain flight speed is required.
这个应用程序本身的概念原理是非常简单的：通过一种非常慢的百叶窗速度连续抓拍四张图，然后串联起来形成动图。
The concept itself is relatively simple: it grabs four photos in succession using a relatively slow shutter speed and then links them together to form a gif-like image.
经过计算分别获得各个时窗内动校正速度误差，而静校正量的计算仍然遵循地表一致性原则。
It will obtain the NMO velocity error after calculating each time window in accordance with surface consistent principle.
