Research On Laser's Transmitting Simulation

Laser-guided weapons and the continuous development of photovoltaic technology and the extensive military use of patterns and processes of modern warfare had a growing influence. Laser confrontation, often encounter the problem of atmospheric transmission, laser transmission in the atmosphere, subject to the impact of various atmospheric conditions, these effects can be divided into linear and nonlinear, in which the linear effect Including atmospheric molecular and aerosol absorption and scattering, nonlinear effect is the Raman scattering, hot halo effect, the size and laser power intensity are closely related.System simulation model by establishing effective, you can fight in the optical transmission characteristics of the laser, smoke interference effective assessment has become an effective adjunct to weapons testing.Based on the atmospheric transmission model and the Smoke Screen assessment mathematical model, software engineering methods, combined with simulation principle, the first tool designed using Rational Rose software needs analysis, and design a software function modules, and finally through the development of software Coding.This article focuses on theoretical models of various simulation studies and the design of system simulation software, the simulation model, the focus on the following aspects:1,The atmospheric transmittance:The main air-ground mode as slant path atmospheric transmission model and ground-ground level atmospheric transmittance model.2,The smoke of the interference mechanism and evaluation principles:from the tactical use of smoke flares, smoke interference mechanism analysis, three aspects of the principle of interference assessment, discusses the actual combat missiles, ships, smoke screen between the three, in theory, how to interfere with missile smoke Ships of the threat assessment model for the Smoke Screen basis.3,Smoke Screen assessment model:According to the semi-active laser-guided and smoke the general guidance law the principle of the use and evaluation, we ship, the movement of smoke and missile mathematical modeling, computer simulation of smoke through the confrontation process, given The moderating effect of smoke.This culminated in the adoption Rational Rose tools and software development tools to develop simulation software, the focus in the simulation software needs analysis, through a detailed needs analysis to determine the function of the software modules, the simulation system, the window interface, algorithm design.The software is transmitted through the laser radiation and shielding effectiveness of smoke simulations, can be a lot of field testing, such as smoke interference test, the laser interference test bias cited reference.As smoke spread by the atmospheric diffusion, air humidity, wind direction, wind speed, sea state and other uncertain factors, coupled with shells and bombs have exploded between the interaction, within the limited time we are unable to establish an accurate mathematical model, in order to Software is more practical as a useful complement to field trials, we need to improve the future of each model, especially for smoke and atmospheric diffusion theory model of the research will focus our future efforts.In order to accurately simulate the real conditions and the physical effect of smoke spread, get into graphic with the real operational environment consistent results, we need to smoke after a more accurate diffusion model, so that guiding of external field test the practical significance.
