Number Aperture的意思|示意

With the same condition, such as the number of sensors, array aperture and the interested directions are the same, the uniform circular array performs the best.

在阵元个数相同、阵列孔径一致以及考察方向为全向的条件下，对比各个阵列的测向模糊和精度，最终得到圆阵为最优阵列形式的结论。

The effects of lighting wavelength, coherent coefficient, aperture number and defocusing to image quality can be studied with this method.

用于研究照明波长、相干系数、数值孔径及离焦等对成象质量的影响。

Under the optimization constraints of the number of element, the aperture and the minimum element spacing, the MGA has been utilized to reduce the peak sidelobe level (PSLL) of the array.

在约束阵列孔径和阵元数的条件下，高效地实现了任意最小阵元间距约束下抑制峰值旁瓣电平(PSLL)的稀布阵综合。

The conventional spatial smoothing algorithm has low array aperture utilization and complex calculation process. And it's smoothing frequency is limited by the number of array sensors and sources.

常规的空间平滑算法存在着阵列孔径利用率低、计算过程复杂的缺点，另外，其平滑次数受阵元数及信源数的限制。

The aperture size (area of the aperture) of a lens could be calculated from focal length and the correspondent f-number.

光圈孔的大小，可从镜头的焦距与焦距比数中计算出来。

The rule is that the smaller the number, the wider the aperture and the more light that can hit the sensor.

规则是数字越小，光圈越大，能到达传感器的光也越多。
