The presence of suspended particles in the atmospheric environment has a significant impact on the detection performance of pulse laser fuse detection systems. Based on the transmission characteristics of pulse laser fuse in particle atmosphere and Mie scattering theory, a particle backscattering model is established, and the necessary conditions for the successful reception of laser beam by photoelectric receiver are determined. By taking into account the transmission time and frequency of the backscattering photon as well as the photon weight after the collision between the photon and the particle, a multi-factor calculation model of laser emission power is constructed, and the mathematical model of the echo power of the system receiving ground targets is derived. Through simulation experiments, the paper obtains the echo characteristics of pulse laser in various detection scenarios. An analysis is conducted on the backscattering characteristics of smoke particles under different laser pulse widths, mass concentrations of smoke particles, and missile-target intersection distances, revealing the impact patterns of these conditions on scattering occurrences and echo results. These research findings provide a basis for exploring methods to enhance the detection performance of laser fuses in complex environments.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
