Based on the theory of laser atmospheric transmission and laser field test, the energy characteristic model testing and establishing method of far field laser spot energy / power based on equivalent measure is proposed. The relevant simulation module and model are also designed. The main factors influencing the simulation of far-field laser signal energy are analyzed: the far-field transmission transformation model of laser beam, the model of atmospheric transmission effect (atmospheric scattering effect model, atmospheric energy absorption effect model, atmospheric turbulence influence model), target diffuse reflection model And spot jitter and background energy simulation model, combined with the typical operation process gives some modeling and simulation evaluation results. Finally, the influencing factors affecting the energy simulation of far-field laser-guided signals are analyzed.
