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 width of a laser beam is much thinner compared to a radar.
激光光束的宽度是苗条多了一个雷达相比。
Angular resolution of a real aperture radar is limited by the beam width of the radar antenna.
一般非综合孔径雷达的方位分辨率受天线波束宽度的限制。
