Abstract:The aim of simulation research is to provide effective guidance for scientific design and performance evaluation of laser detecting system. The simulation modeling is presented aiming at certain laser detector system. The laser echo power formulation and photo-electricity transform model are analyzed. The simulation of laser detecting system is carried out based on these models. Ultimately, the models mentioned are proved effective by detecting sample experiments. The simulation aiming at certain typical detecting target can deduce that the laser detecting system can realize target identification exactly and distinguish targets with different figure by the difference of echo waveform.
