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) 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 of distance does not exceed 0.15 m in smoke interference environment.

Floating-point (FP) multiplication finds application in image and signal processing. This paper presents a hardware implementation of optimized IEEE 754 single precision floating-point multiplier. The design is simulated using Modelsim and synthesized using Virtix E Xilinx ISE. An improvement of 57.77% in area and 44.52% in delay is shown.
