摘要
机载激光遥感系统由激光发射与接收、回波采样、姿态测量、信息处理等部分构成,利用激光回波信号的相关信息确定目标的后向散射率、类型和灰度,生成遥感地表影像。其系统仿真将激光发射机、运载体飞机、大气、地面目标等模块的相应参数作为输入,通过对接收机输出的解算,导出地面目标的位置和后向散射率,并对成像点进行粗插值和区域插值处理,最终获得目标三维地表影像。
The imaging system of airborne laser remote sensing is composed of laser transmitter/receiver, echo sampling, gesture measure and information processing, the back scattering rate, type and gray scale of object is defined by the correlation information of laser echo signal to create remote sensing the earth surface imaging. Corresponded parameters of laser transmitter, carry-plane, atmosphere, earth object etc were sent models of simulation system, output of receiver was calculated, and the position and back scattering rate of earth object was educed. Thickness interpolation in imaging spot and area interpolation processing was carried, and finally, 3D earth surface imaging was obtained.
