| The study of spectrum scattering and reflection of complex target is a part of æƒnfrared characteristic collecting and modeling of representative martial target?and ætudy of scattering property of target?that plays an important role in the development of the national defense and economy0 It can provide technical supports to hiding and antihiding~ control and guiding using infrared light, fusec technique~ system emulating, extract the target characteristics and recognize the target, etc 0This dissertation develops the spectrum scattering and reflection characteristic of complex target in oceanic and celestial background0 The special contributions are:1.]n the academic study of rough surface scattering, we have computed the single or bistatic radar cross section (RCS) using perturbation method and compared the results with experiment02.This dissertation builds the geometrical model of complex target (Fl 6) using smooth curves and surfaces theory and anti- educing control points; The target have also been hiden by facet mh03.In the study of rebuild geometrical model of complex target, We also use the SGJ?three dimension graphics standard OpenGL and NURBS (Non-Uniform Rational BSpline) surfaces0 This dissertation also realize auto-hiding by three dimension graphics accelerated card and RCS computing using graphics electromagnetic04.The oceanic slope and surface radiation are given by using international standard oceanic spectrum model JON SWAP ; The formula of computing zenith and azimuth angle in all conditions and numerical result are given: We also gained the spectrum permeable ratio of atmosphere and background radiation using LOWTRAN705.We develop software version 1.0 of æcattering and reflection of complex target to infrared radiation? this software has good man-machine interface0 The results of scattering and reflection of complex target to oceanic and celestial background are gained~ this include space distributing and spectrum distributing0...
