The Modeling Simulation Of Smoke Screen And Its Effect Analysis

Smoke which used as interfere has a long history and works widely by now. It has been a high effective interfere method in modern war, so the modeling simulation of smoke screen has been a big important research project. In this paper, the theoretical model of smoke screen is the concentration distribution of the continuous point source-Gaussian model. And it researches a method base on Vega particle system with consistency field. It can simulate dynamic smoke screen in real time, programmed with using the API interface of MFC&Vega for simulation, and gives final result of simulation test also.Smoke screen has big effect in absorption and scattering to light signal, and has extinction affect to visible light, infrared light and laser. This paper researches on the transmissivity of different waveband under smoke screen interference, aims at CCD detector search tracking system, infrared thermal imaging system and laser range finder system to make analysis and get influence result of detector distance with smoke screen interference.
