Abstract

In order to analyze the backscattering characteristics of graphite smoke in pulsed laser fuze, a pulsed laser fuze detection model in graphite smoke was established based on Mie scattering theory and Monte Carlo method. We simulated the graphite smoke backscattering echoes of pulsed laser fuze at various laser pulse widths and smoke visibilities. The results show that the normalized echo peak intensity of graphite smoke approximately exhibits an exponential growth relationship with the pulse width, while a power function decay relationship with the visibility. Compared with the emitted laser waveform, the graphite smoke echo waveform is distorted, presenting an asymmetrical feature with steep rising edge and gentle falling edge. Moreover, the narrower the laser pulse width, the greater the smoke visibility, and the more obvious the echo waveform asymmetry. This study provides a theoretical basis for exploring ways to enhance the detection performance of pulsed laser fuze in the graphite smoke environment.
