分布式星载雷达突破了单星雷达受功率孔径积的限制，具有更远的探测距离；

Compared to single-satellite radar, a great power-aperture product with longer detection range can be achieved by distributed space-based radars.

微光观察仪是在微弱光条件下用来观察目标的一种仪器，探测距离是它的一项重要指标。

Image intensifier is apparatus which can objects under weak light conditions, the range is one of its parameters.

目的探讨探测距离对SPECT断层分辨率的影响。

Objective This study investigated the effects of detecting distance on SPECT tomographic resolution.

而细光束照明时，散射谱强度分布峰值随探测距离的增加而减小，半宽值则逐渐增大。

But the peak value reduces gradually and FWHM increases as the detecting distance increases under the slim beam illumination.
