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

Blog Article

In a smoke environment, ethical nutrients mega magnesium powder citrus 450g 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) 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 here FMCW laser fuze.The absolute error of distance does not exceed 0.
