Infrared Imaging Simulation Of Aerial Target In Multi-band

Target and interference infrared image simulation is an important means to study the infrared radiation characteristics of various parts of the target,and it is also an important reference for improving infrared countermeasures.The research on the radiation characteristics of domestic targets and interference has made some progress.At present,the infrared image simulation of aerial targets has the disadvantages of single band,simple model,and poor realism.To overcome these shortcomings,this paper realizes high realism multi-band complex real-time simulation system.This paper analyzes the whole process of aerial target and its interference imaging,and establishes a "target-environment-interference" simulation theory model.According to the skin's aerodynamic heating model,the skin's Schlick BRDF model,the tail flame CG line model,MODTRAN infrared atmospheric radiation and transmission model for each part of the radiation calculation.Based on an in-depth understanding of the OGRE system,Using GPU-programmable rendering technology to realize skin image,tail flame,decoy bomb,infrared image rendering of atmospheric effect,This method has a higher rendering speed than traditional infrared simulation technology and has a more concise program structure.Using particle system technology,bulletin board technology,trajectory animation technology,to perform movement and dynamic effects on aircraft tail flame,decoy bomb,smoke screen simulation,which improves the fidelity of the simulation model.Using OGRE synthesizer technology to simulate the infrared system noise and using pseudo color technology to visually enhance infrared images,which make the simulation system more complete.
