The detection ability of laser fuze is easily disturbed by smoke, which causes false alarm. In order to study on the backscattering characteristics of pulsed laser fuze in smoke, the relevant model based on Mie scattering theory and Monte Carlo method was established, and the backscattering signal in smoke was simulated using 905 nm pulsed laser. To verify the accuracy of the model, the actual peak voltage was compared with the simulated normalized intensity and correlation analysis was conducted. Then, the backscattering characteristics of the pulsed laser fuze under different smoke concentrations, length of pipes and distances were analyzed. Finally, the influence of different smoke environment was obtained. The results can provide support for the anti-smoke interference of the pulsed laser fuze.
