The measuring method of the weak energy of 1064nm laser scattering in laser guided halfware (HWIL) simulation is introduced, and the laser scattering weak energy measuring system is designed and constructed. Combined with the Mie scattering theory of indoor atmospheric path, the laser scattering weak energy prediction model was analyzed and verified by the measuring system. The results of the prediction model are in good agreement with the actual measurement results. The system can meet the needs of lab laser atmospheric transmission weak laser energy measurement Claim. The main factors influencing the actual simulation results are analyzed. It is pointed out that the reasonable spatial layout and the necessary interference energy control measures should be taken according to the test requirements and test methods to reduce the influence of extra interference energy on the simulation results.
