Notice of RetractionThe temperature modeling of the moving armored vehicle based on finite element method
Due to the decline of the viability and battle effectiveness of the electronic countermeasure armored vehicle caused by intense infrared radiation (IR), the temperature model is built for the IR characterizations of moving target. While taking the effect of radiation, convection and heat transfer into consideration, the mathematic description and simulation of the temperature model are carried out with finite element method (FEM) in the processes of sub-domains partition, node determination, control equation construction, boundary condition determination, equation discretization and iterated calculation. The comparison and analysis of the temperature distribution of typical parts between the simulated results of the FEM and the actual measured value are carried out with the same parameters. It indicates that the results with the application of the FEM approaches the actual measured value more with a better precision.
A Comprehensive Methodology For Thermal Signature Simulation Of Targets And Backgrounds
For the past several years the U.S. Army Tank-Automotive Command (TACOM) has sponsored the development of computer models to simulate the thermal signature of concept vehicles. The entire simulation process involves the prediction of target and background temperatures, creation of the 3-D graphics database, and the addition of atmospheric and sensor effects to produce a simulated infrared or thermal image. This paper also describes the model integration necessary to create thermal signature animations for concept vehicles. Each model is described in some detail along with the appropriate interface to the other thermal models.
Development of the TACOM (Tank Automotive Command) Thermal Imaging Model (TTIM). Volume 1. Technical Guide and User's Manual.
Abstract : This report describes TACOM's Thermal Imaging Model (TTIM). The model allows measured or modeled scenes to be viewed by a simulated imaging sensor. The resulting scene is then displayed for observer evaluation. Currently, the model is operating on a Digital Equipment Corp. VAX 11/750 computer at US Army Tank-Automotive Command (TACOM) in Warren, MI. Keywords: FLIR modeling; Thermal imaging system modeling; and Image simulation.
