Fous o 1 2 3 Energy tJ] 0 1 Time [ns] x 10* Figure 21. Waveform of several locations 4. CONCLUSIONS In this study, we attempted to simulate waveforms of lidar. For the waveform simulation, we performed the modelling of backscattered return pulses by sub-beams. First we defined the ray model of sub-beams by dividing a beam, and computed the intersecting point between the defined rays and target surfaces. In radiometric simulation, received energies of sub-beams are calculated using laser range equation with the ranges computed in geometric simulation. Finally, we generated the waveform signal by combining the return pulses, and add the signal noise created using NEP. We confirmed that the waveform data was successfully simulated by the proposed method. The results of this study will be helpful to understand waveforms in educations and also develop various applications processing waveform data. REFERENCES Blanquer, E., 2007.
