FMCW Laser Fuze Multiple Scattering Model and Accurate Fixed-Distance Algorithm in a Smoke Environment

Blog Article

In a smoke environment, suspended particles can scatter and absorb laser photons, making target echo signals extremely weak and difficult to extract and identify, which causes obvious difficulty in fixed-distance of laser fuze.In this paper, the multiple scattering model of frequency-modulated-continuous-wave (FMCW) Party Games laser fuze in a smoke environment was established.This model simulates multi-path propagation and multiple scattering of photons.At the same time, we use the correntropy spectral density (CSD) algorithm for accurate fixed-distance of FMCW laser fuze.The absolute error Desktop Vaporizers of distance does not exceed 0.
