The software of atmospheric scattering off-axis detection of 1.064 μm laser was developed by MAT-LAB. Using this software,scattering radiative parameters can be calculated and the corresponding curves can be drawn in various atmospheric propagation modes. Besides,the evaluation of scattering interceptive range for 1.064 μm laser warning and the scattering characteristic of guiding laser beams were simulated. The results show that scattering pa-rameters in various atmospheric conditions can be predicted,which provides a convenient and fast tool for system de-signers and project users.
