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。

The key technique, therefore, is how to control the divergence of the angular velocity calculation error and improve the calculation precision.

所以，抑制角速度解算误差的发散，提高其解算精度是该项技术研发的关键。
