A test method of 1064 nm laser scattering weak energy in laser-guided halfware in the loop simulation was introduced in this paper.The scattering energy in emergence of a certain type of laser was tested and analyzed.The distributing rule of scattering energy was summarized and the simulation model was established.The results show that in near field the laser′s scattering energy is some times larger than which scatted by aerosols and the scatterly angel is wide.But in the far field,the laser′s scattering energy is significantly lower than which scatted by aerosols.Therefore some measures such as aperture blocking must be taken to deal with scattering energy in emergence in near field simulation test and it′s of great significance to reduce the measurement error.
