Thirdly, the fog attenuation for Gauss beam propagation is discussed, and the computational results are compared with those with plane wave incidence.

对高斯波束在雾中的衰减进行了讨论，并将数值计算结果与平面波结果进行了对比。

These all will produce some other effects that would strongly affect the transmission of laser signals, especially attenuation, coruscation and dithering of beam.

上述一系列效应对激光信号的传输产生巨大的影响、其中最为重要的影响效应有衰减、光束闪烁及抖动效应。

The operating distance of a laser radar system is determined on pulse energy, pulse width, beam divergence angular, atmosphere attenuation, target reflection, receiver sensitivity and so on.

激光雷达系统的作用距离由下列因素决定：脉冲能量、脉冲宽度、光束发散角、大气衰减、目标反射率和接收机灵敏度等。
