摘要

Fog backscattering is one of the major reasons for false alarming in the laser proximity fuze. However, its influence to the frequency modulated continuous wave (FMCW) laser fuze has not been well studied. In this paper, a Monte-Carlo simulation model of the FMCW laser transmission in fog based on the laser detection principle and the Mie scattering theory was established. The simulation results showed that the fog backscattering signals spread the beat signals spectrum. Experiments were also performed in a simulated laboratory environment and the results confirmed the findings. Therefore, this study can greatly assist the signal identification between target reflection and fog backstattering and potentially avoid the false alarms. (C) 2016 Elsevier GmbH.
