摘要
本文介绍了脉冲激光束远区场的时空分布，导出了机载脉冲激光对地面扫描探测时回波脉冲的时域表达关系，通过数值计算得到了回波脉冲波形及其有关参数随扫描倾角的变化规律，结果表明不同波束倾角时回波脉冲特征发生了明显的变化。
In this paper,the spatial and temporal distribution of the pulsed laser beam in a far field is introduced. An expression of the return pulse power in time domain is deduced for an airborne pulsed laser beam scanning and sounding over the ground. The waveforms of the return pulse, its main characteristics and the relations between them and the scanning angle of beam are obtained. It is indicated by the conclusion that characteristics of the return pulse vary distinctly with the scanning angle of the beam.
