| 摘 要： | 从激光测高雷达回波能量分布模型和地表模型入手,详细介绍了基于IDL的激光测高雷达回波的仿真过程及仿真程序各个模块的功能,用Pearson相关性方法将仿真所得波形与实测回波波形进行了分析比对,二者的相关性系数达到90%以上,并分析了回波脉冲波形随测高系统参数和地表参数的变化情况.该方法可以直观有效地对不同地表的回波进行仿真,为激光测高雷达的回波分析提供了重要的技术手段.

| Abstract: | Based on the spatial distribution of laser beam intensity of laser altimeter and terrain characteristics mode,the simulation process of lidar waveforms and the function of each model of simulation program based on IDL were presented in detail.The modeled and actual lidar waveform pairs were compared using the Pearson correlation,and the correlation coefficients were always larger than 90%.The variation of the waveform with different parameters of the laser altimeter and the terrain was analyzed.The simulation is a direct and effective method to model the lidar echo from arbitrary terrain,which provides an important technical mean to analyze the lidar waveforms |
