因此，加速度搜索对小于50分钟的轨道周期不敏感，而边频带搜索对大于3分钟的轨道周期也不敏感。

Thus, the acceleration search becomes significantly less sensitive for orbital periods shorter than 50 minutes. The sideband search loses sensitivity for orbital periods longer than 3 minutes.

当连续图像信号的频带处于一个圆形区域之内时，正六边形点阵结构的采样密度比矩形点阵结构的采样密度要降低13。

However, when the signal is a circularly band-limited, the minimum sampling density for a hexagonal sampling lattice is 13.
