Research Of The Explosion Impact On The Laser Transmission Channel

The paper on the basis of the product produced by explosion and laser channel transmission characteristics. in view of the actual situation of the simulation and application, based on the actual combat of simulation environment and the specific analysis of the theory model. discusses the attenuation characteristics of the laser communication in explosive environment and the function relation between attenuation and TouDanLiang, at the same time deduce the atmospheric turbulence intensity of the describing function. the paper main research content is as follows:1. the smoke which is produced by explosion influence on the attenuation of laser under TNT equivalent. explosions produce smoke of laser transmission influence not only the other factors, such as weather conditions, and the need to consider is TouDanLiang and laser transmission attenuation function relationship. So this paper will take smoke diffusion model and laser transmission attenuation theory as the foundation, choose van de Hulst myopia method, the establishment of TouDanLiang and laser transmission attenuation function relation, and then the simulation the transmittance when laser through the smoke from an explosion environment.2. The relationship between the blast parameters and the intensity of channel turbulence. atmospheric refractive index structure constant separation constant term,pressure and no contains pressure items, on the basis, researching the blast shock wave influence on the surrounding pressure, and analysis the explosion environment through a single shock wave produced by the pressure of anchors R mean pressure to replace the rationality of the instantaneous pressure, finally arrive at atmospheric refractive index structure constant and shell charge and the relationship between the shock wave propagation position. For the study of the local turbulence produced by the explosion wave generation in optical transmission making a preliminary study.In this paper, through the study of the above two aspects, obtained the simple relationship between the interference intensity and bombs laser in battlefield transmission channel.for the future, provided certain reference for studying of laser transmission in real-time battlefield environment.
