这给出了通过借助于在空间邻域（例如倾斜圆柱体）中堆叠相邻激光波形来模拟更大的激光足迹来增加SNR的动机。一方面，这意味着空间分辨率的降低;但另一方面，这意味着在检测水面和评估水柱浊度方面的结果的可靠性增加。
This gives the motivation for increasing the SNR by simulating a bigger laser footprint by means of stacking adjacent laser waveforms in a spatial neighbourhood, e.g. a slanted cylinder. On the one hand, this implies a reduction in spatial resolution; on the other hand though, it means an increase in reliability of the results, both in the detection of the water surface and enabling for assessing the turbidity of water column.
